Algebraic Function Teacher Resources

This is an interesting problem that approaches higher-degree polynomials from a different perspective. Given a third-degree polynomial, two known zeros, and a y-intercept, find the value of the polynomialÕs coefficients. This problem...

It's the video your algebra class has been waiting for - Sal explains the quadratic formula! He describes it as "one of at least the top five most useful formulas in mathematics" and recommends that it be memorized, provided one also...

This video proves the helpful change of base formula for logarithms. The proof steps may need to be more intuitive to most logarithm learners, but the algebraic manipulation shown using logs is interesting.

Starting a new set of SAT practice problems from The Official SAT Study Guide (page 518), Sal takes students through some straightforward questions involving basic algebra and functions. However, as every math teacher and student knows,...

Graphing skills are a focus of this video, making it ideal for students who have a hard time using slopes and functions. Additional problems involve visualization, geometric figures, and algebraic factoring.

Transitioning between algebra and geometry is no problem for Sal as he deftly solves these practice SAT problems. Mathematicians who have a hard time moving between skill sets will appreciate the way that Sal addresses each new problem...

Fans of algebra, geometry, and hamsters will enjoy this video, which finishes this practice test with problems 15-16. Sal carefully, methodically, and efficiently takes students through the necessary steps for solving increasingly...

Carefully reading word problems is a skill that many students neglect due to time constraints or test anxiety, and Sal models how to do so in this video. Both algebra and geometry are featured in problems 10-12 of the practice SAT.

Working through problems 11-14 on the practice SAT, Sal shows students how to solve problems that look complicated, but can actually be quite simple. Problems involving algebraic expressions and geometric distances make up the rest of...

In this algebra worksheet, students find the domain and range of composite functions. They use graphics from an unspecified text to create the graph of the inverse of the drawn function.

In this college level algebra instructional activity, pupils determine the domain and range of a function, determine the average rate of change given an interval and the function, and graph a polynomial function. The two-page...

Writing a quadratic equation in standard form gives values for a, b, and c that can be used to find several pieces of information about the graph of the equation. Knowing a, b, and c-values allows one to find the axis of symmetry, the...

In this algebra worksheet, young scholars look at 4 sets of relations and determine if they are functions. Students are provided with the graphs of three functions and determine the function value. Two relations are graphed on the...

In six days Tina gets exponentially better at the number of times she can jump rope. Let's create an equation and see how many times Tina can jump rope on the sixth day. First identify the variables. Next make a table, then plug in the...

Trying to find the vertex of a quadratic equation? Remember that the vertex is the minimum or maximum point of the quadratic equation and can be identified on a graph of the equation. First use the axis of symmetry formula to find the...

In this calculus worksheet, students solve problems using integration. They solve exponential functions using differentiation formulas. There are 12 problems with an answer key.

In this algebra worksheet, students combine like terms and solve for the given variable on 12 linear equations. Ten of the equations require students to use the distributive property.

How do you graph a quadratic function efficiently? Explore graphing quadratic functions by writing in intercept form with a lesson that makes a strong connection to the symmetry of the graph and its key features before individuals write...

High schoolers collect height versus time data of a bouncing ball using the CBR 2™ data collection device. Using a quadratic equation they graph scatter plots, graph and interpret a quadratic function, apply the vertex form of a...

Give your class a concrete example of exponential growth and decay using this hands-on activity. These Algebra II lessons allow for the exploration of exponential growth and decay models, as well as the discovery of the patterns of...

Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense...

Get out those thinking caps and apply graphing functions to a real-world problem. Use the TI-83 graphing calculator to evaluate algebraic expressions that are imbedded in a series of real-world scenarios. A great instructional activity!

Students differentiate between a relation and a function. In this algebra lesson plan, students identify a pair of coordinates as being a relation or a function. They analyze graphs for function as they solve word problems.

In this problem solving activity, 6th graders determine if 4 functions are exponential growth or decay, sketch 4 graphs and compare 2 sets of functions. Students write the rule, linear or exponential, for 4 tables.
