Question

F(x) = 2x² +2
g(x) =-3x-3
Find f(-2) and g(2).

Answer 1

`f( - 2) = 10 \\ g(2) = - 9`

Explanation:

`f(x) = 2x { }^(2) + 2 \\ f( - 2) = 2( - 2) {}^(2) + 2 \\ = 10 \\ \\ g(x) = - 3x - 3 \\ g(2) = - 3(2) - 3 \\ = - 9`

Answer 2

Explanation:

f(-2) = 2(-2)^2 + 2 = 2(4) + 2 = 8 + 2 =10

g(2) = -3(2) - 3 = -6 -3 = -9
