Question

Given the function g(x) = (5 - x)^3 , what is the value of g(2)?

Answer 1

9(2)=27 is your answer

Answer 2

g(2) = 27 is the answer.

Explanation:

If the function is g(x) = (5 - x)³

By expanding (5 - x)³ = 5³-3.5²x + 15x² -x³

g(x) = 125 - 75x + 15x² - x³

Now g(2) = 125 - 75×2 + 15×(2)² - 2³

g(2) = 125 - 150 + 60 - 8

= -25 + 60 - 8

= 35 - 8 = 27

Or directly putting the value x = 2 in g(x) we get

g(2) = (5 - 2)³ = 3³ = 27

Therefore g(2) = 27 is the answer.
