Question

I’m so confused. I don’t get it.

Answer 1

Explanation:

f(-6) means plug in -6 into f(x)

g(6) means plug in 6 into g(x)

f(-6)

2*
`(-6)^(2)`-3*(-6)

2*36 + 18

72 + 18

90

g(6)

-4*(6) + 2

-24 + 2

-22

Answer 2

f(-6) = 90

g(6)= -22

Explanation:

f(x) = 2x²-3x. We are asked to find f(-6). What this means is we must find the output of function f when x is equal to -6. So, we substitute: 2(-6)²-3(-6). This breaks down to:

72 - (-18), or 72+18. Therefore, f(-6) = 90.

We do the same with g(x)= -4x+2, where we must find g(6). We substitute again: -4(6)+2. This breaks down to -24+2, or -22. So, g(6) = -22.
