Sketch the graph of the function and check the graph with a graphing calculator. Before doing so, describe how the graph of the function can be obtained from the graph of a basic exponential function.

Solution

x=f(x)

x=-2 then f(x)=-8

x=-1 f(x)=-2

x=0 f(x)=1

x=1 f(x)=0.66

x=2 f(x)=0.88

x=3 f(x)=0.96
