#### Answer

Refer to the image below for the graph.
The red graph is $f(x)$ while the blue graph is $g(x)$.

#### Work Step by Step

To graph the given function, perform the following steps:
(1) Create a table of values for each function by assigning values to $x$ then solving for the corresponding $y$ value of each one. A graphing calculator may be used to do this.
(refer to the attached table below)
(2) Plot each set of ordered pairs from the table of values then connect the point in each set using a smooth curve. The red graph is $f(x)=4^x$ while the blue graph is $g(x) = 7^x$.
(refer to the attached image in the answer part above)
