The completed chart is attached as an image

------------------------------------------------

Plug x = -2 into f(x) to get:
f(x) = 9*x + 7
f(-2) = 9*(-2) + 7
f(-2) = -18 + 7
f(-2) = -11

Do the same for g(x):
g(x) = 5^x
g(-2) = 5^(-2)
g(-2) = 0.04

----------------------------------------
Plug x = -1 into f(x) to get:
f(x) = 9*x + 7
f(-1) = 9*(-1) + 7
f(-1) = -9 + 7
f(-1) = -2

Do the same for g(x):
g(x) = 5^x
g(-1) = 5^(-1)
g(-1) = 0.2

----------------------------------------
Plug x = 0 into f(x) to get:
f(x) = 9*x + 7
f(0) = 9*(0) + 7
f(0) = 0 + 7
f(0) = 7

Do the same for g(x):
g(x) = 5^x
g(0) = 5^(0)
g(0) = 1

----------------------------------------
Plug x = 1 into f(x) to get:
f(x) = 9*x + 7
f(1) = 9*(1) + 7
f(1) = 9 + 7
f(1) = 16

Do the same for g(x):
g(x) = 5^x
g(1) = 5^(1)
g(1) = 5

----------------------------------------
Plug x = 2 into f(x) to get:
f(x) = 9*x + 7
f(2) = 9*(2) + 7
f(2) = 18 + 7
f(2) = 25

Do the same for g(x):
g(x) = 5^x
g(2) = 5^(2)
g(2) = 25

----------------------------------------

Write each of the results into the table (again see attached)

In the last row of that table, we have x = 2 lead to f(x) = 25 and g(x) = 25

So f(x) = g(x) has the solution of x = 2

The solution is x = 2 and not x = 25
25 is the output f(x) and g(x) value. It is not the x value.

Answer: choice C) x = 2

-11                       1/25
-2                         1/5
7                           1
16                         5
25                         25

x = 25
(I'm guessing your suppose to find a common answer)
hope this helps
