Parent Graphs of Exponential and Logarithmic Functions

Parent Functions of Exponential and Logarithmic Functions
The graph to the left shows the parent graphs of both the decay and growth exponential and logarithmic functions. As you can see, the parent equation for an exponential function is y = ab^x. You can also see that the parent equation of a logarithmic function is y = a+b lnx

Parent Graphs of Constant, Identity, Polynomial, Square Root, Absolute Value, Greatest Integer and Rational Functions

Other Parent Functions
The graph to the right shows the parent graphs of the constant (y = 0), identity (y = x), polynomial (y = x^2) and (y = x^3), square root (y^2 = x), absolute value (y = lxl), greatest integer (y = [x]), and rational functions (y =1/x or x^-1).
