Rational and Radical Functions Teacher Resources

A mathematics video explains the parts of an equation and reviewing relevant vocabulary. Next, it covers one-, two-, and multi-step equations. It includes a few example problems for each type as well.

Why did the variable add its opposite? To get to the other side. A video introduces the concept of variables. It compares and contrasts independent and dependent variables in a variety of problems.

The representation of a relationship really depends. The difference between dependent and independent variables is the focus of a short video that also includes examples of determining the types of variables. The presenter makes the...

No matter how it is written, it still is a line. A video shows class members how to take points and write the equation of the line that goes through those points. It then outlines how to develop the equation whether...

Provide the definitions of parallel and perpendicular lines, as well as the relationships between their slopes. Two examples explain the process of finding the equation of either a perpendicular or parallel line to another line through a...

What's my line, anyway? A video covers the aspects of finding an equation of the best-fit line for a set of data. It works through plotting the points to drawing a line that appears to represent the data. The presenter suggests finding...

Correlate the responses to identify the cause. A resource presents how individuals sometimes confuse the issue between correlation and causation. The video provides examples of different variables that are correlated — but one does...

Is it better to be average or an outlier? It all depends on your perspective! The video explains the impact an outlier has on central tendency. Using multiple examples to solve for mean, median, and mode, the video proves that having an...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The learning exercise includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Use this video to show your learners an example of how to translate word phrases into an equation to solve a real-world problem. The presenter begins with a review of how to use cross products to solve a proportion, including how to do...

Finding the length of the hypotenuse of a right triangle can be done in two ways as shown in this video. First, the hypotenuse is found using the Pythagorean Theorem. Next, the distance formula is used to solve the same problem. 

We all know linear equations are special, but the direct variation equation is extra special! The video begins with a set of data to illustrate a direct variation relationship. It then completes examples of writing direct variation...

Demonstrate how to use a box and whisker plot to place a line of best fit accurately with an educational video. It begins with a review of box and whisker and line of best fit, and then uses an application problem to describe the...

A look into the graphs of rational and radical functions.

Confused about graphing or just need a refresher? This explanation focuses on graphing higher-power polynomials along with radical functions, rational functions, and piecewise functions. Plenty of examples are included.

Lesson 2 of 4 for Passport to Advanced Math. Students will build quadratic and exponential functions that model a given context; solve radical equations; work with rational expressions, including fractions with a variable in the...

[Free Registration/Login may be required to access all resource tools.] This lesson applies the laws of exponents to rational exponents.

This comprehensive study guide highlights the main terms and formulas needed to review irrational numbers and radicals. Examples are included.

Practice finding the formula of the inverse function of a given polynomial, radical, or rational function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This resource provides an overview of graphing, giving examples of general polynomial, radical, rational, and piecewise functions. Also includes advice on common mistakes made by students.

This site reviews the basic properties of exponents, and explains rational exponents and exponential functions, including those with base "e." Provides examples and lots of exercises.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

This lesson provides basic instruction on the major concepts in algebra. Content includes a focus on fractions, units of conversion, complex numbers, quadratic equations, factorization and roots of polynomials, solving equations, systems...
