F(x) = 4x - 4, g(x) = - 3x² + 2x - 3, and h(x) = - 2x^2- 5, find f(-4)

-20

Step-by-step explanation:

f(x) = 4x - 4

f(-4) = 4*-4 - 4

f(-4) = -16 - 4

f(-4) = - 20

f(x) shares many of the properties of y so you could think of this question as y = 4x - 4The difference is as in this question that f(-4) conveys the message that wherever you see an x on the right side of the equation, you put -4 in it's place.That's what was done on the second step.
