g(x) = 5^x is your answer
Plug in increasing numbers for x to get the output.
For example: when x = 1
f(1) = 5(1) = 5
g(1) = 5^(1) = 5
when x = 2
f(2)= 5(2) = 10
g(2) = 5^(2) = 25
when x = 3
f(3) = 5(3) = 15
g(3) = 5^(3) = 125

From the example above, we see that g(x) = 5^x is your answer

If you would like to write a * b + c in simplest form, you can do this using the following steps:
a = x + 1
b = x^2 + 2x - 1
c = 2x
a * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1
The correct result would be x^3 + 3x^2 + 3x - 1.
The answer is c, -1 or -7
Hope this helped :)
The easy way is just to divide by 3
15% /3 = 5%
Since you have divided the % by 3 you can divide the 375 by 3
375 / 3 = 125
Answer 125
