Parent Functions And Their Graphs - How To Graph Elementary Functions?

In math, we often encounter certain elementary functions. These elementary functions include rational functions, exponential functions, basic polynomials, absolute values and the square root function. It is important to recognize the graphs of elementary functions, and to be able to graph them ourselves. This will be especially useful when doing transformations.

Basic Graphs That Every Algebra Student Should KnowBasic graphs that are useful to know for any math student taking algebra or higher. y = mx + b (linear function) y = x2 (quadratic) y = x3 (cubic) y = x5 y = |x| (absolute) y = √x (square root) y = 1/x (reciprocal) y = 1/x2y = logb(x) for b > 1 y = ax for a > 1 (exponential)y = ax for 0

Exploring Properties Of Parent FunctionsIn math, every function can be classified as a member of a family. Each member of a family of functions is related to its simpler, or most basic, function sharing the same characteristics. This function is called the parent function.

This lesson discusses some of the basic characteristics of linear, quadratic, square root, absolute value and reciprocal functions.

Transformations Of Parent FunctionsLearn how to shift graphs up, down, left, and right by looking at their equations.

Vertical Shifts: f(x) + c moves up, f(x) - c moves down.

Horizontal Shifts: f(x + c) moves left, f(x - c) moves right.
