Austin Rice · Answer 1

F (x) = - 4x x=-3 Y=f (x)

replace - 3 for x so it would then look like: f (x) = - 4 (-3)

Distribute - 4 to - 3

Answer is f (x) = 12

Zayden Mcmahon · Answer 2

So your equation is f (x) = - 4x

If your x=-3, you can rewrite your equation as

f (x) = - 4 (-3)

To find your answer, simply multiply - 4 x - 3 and your answer should come to an answer of - 12
