Question

For g(x)=9x^2-2x find g(-2)

Answer 1

Hello there! How are you today?

First, we need to replace every 'x' with -2 as we are using the function of g(-2).

9(-2^2) - 2(-2)
Simply the parenthesis.

9(4) + 4
Simplify.

36 + 4

40 is your answer.

I hope this helps!

Hello friend
------------------------------------------------------------------------------------------------------
g(x) = 9x² - 2x

g( -2 ) = 9(-2)² - 2(-2)
          = 9×4 + 4
          = 36 + 4
          = 40
