Question

G(x) = x^3 - 5; Find g(5)

Answer 1

g(5) = 120

Explanation:

We want to find g(x) when x is equal to 5, so we can substitute 5 in for x.

g(x) = x^3 - 5

g(5) = 5^3 - 5

Solve the exponent

g(5) = 125-5

Subtract

g(5) = 120

Answer 2

g(5) = 120

Explanation:

g(x) = x^3 - 5;

Let x=5

g(5) = 5^3 -5

= 125 -5

= 120
