Answer:

-2

Step-by-step explanation:

If f(x) = 2x² + 4x - 2

f(-2) = 2(-2)² + 4(-2) - 2

f(-2) = 2(4) + 4(-2) - 2

f(-2) = 8 - 8 - 2

f(-2) = -2

Answer:

It is -18

Step-by-step explanation:

[tex]f(x) = - 2 {x}^{2} + 4x - 2[/tex]

when x is -2, f(x) is f(-2):

[tex]f( - 2) = - 2 {( - 2)}^{2} + 4( - 2) - 2 \\ \\ f( - 2) = - 8 - 8 - 2 \\ \\ f( - 2) = - 18[/tex]
