Question

Suppose f(x)=3x^2-2x Find f (-4)

Answer 1

The answer is 56

Here's how I got my answer:

Step 1: Replace all the x's in the equation. Which leaves us with $3(-4)^2-2(-4)$

Step 2: Solve $-4^2$, which is $16$. That leaves is with $3(16)-2(-4)$

Step 3: Solve $2(-4)$, which is $-8$. That leaves us with $3(16)+8$

Step 4: Solve $3(16)$, which is $48$. That leaves us with $48+48$

Step 5: Simplify $48+48$ to get your answer, 56.

Answer 2

f(-4) = 3(-4)^2 - 2(-4)

f(-4) = 3(16) + 8

f(-4) = 48 + 8

f(-4) = 56

I think the answer is 56 :)
