7.6 Exponential Functions

Definitions What is a linear function? y = mx + b Any function whose graph is a line. Any function with a constant rate of change in y’s. An exponential function is any equation whose independent (input) variable is an exponent. a = initial amount b = growth factor: # repeatedly multiplied x = # times repeated

Example 1: Given the domain x = {-2, -1, 0, 1, 2} find the range. As the x values increase, do the range values increase or decrease? Sketch a graph. Identify the y-intercept.
