Writing and Sketching II

Grow an equation for the exponential graph. Given a graph of an exponential function, class members write the equation of the function provided. The graph labels two points on the graph: the y-intercept and the point where x is one.

The characteristics of parent function vary from graph to graph. Let learners decipher the graph, table of values, equations, and any characteristics of those function families to use as a guide. The nicely organized page...

Find deeper meaning in graphs. Pupils use the knowledge gained from the previous sections in the unit to sketch graphs of a function's derivative. Learners also see how to sketch a graph of a function given the graph of its derivatives....

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts with an intuitive sense of what a function inverse is. Using an example, he then shows how to find the inverse of a function and how the graph of...

Build a function from pieces of other functions. Learners observe how to write a piecewise function from its graph with an instructive video. The video uses all notation and vocabulary related to piecewise functions, as well as...

Though Sal expects viewers to be "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...

We look at several different examples of functions and see what their domain is. Sal writes the domain in a set notion and shows how different functions can have different input values that cause them to be undefined.

Expand your knowledge on exponential growth! A concept video features the definition of an exponential function. Eight problem videos cover graphing exponential functions, identifying exponential growth and decay, and applying...

Determine critical points in the flight of a soccer ball. Pupils use an interactive resource to find the vertex and x-intercepts of the graph of the trajectory of a soccer ball after being kicked. Scholars investigate the trajectory...
