Graphs of Functions

Additional Resources:

In this lesson, we will look at the graphs of six parent functions. The identity function, y = x, the squaring function, y = x2, the cubing function, y = x3, the square root function, y = sqrt(x), the cube root function, y = cbrt(x), and the reciprocal function, y = 1/x. We will also discuss how to find the domain and how to find the range for each function. These parent functions are the simplest form, with no transformations applied. Knowing the basics of these functions will be extremely helpful when studying function transformations.
