find (-4) when f(x) = 4-2x
f(-4)+4-2
f(-4)=-2 Is that correct I am having a hard time with this and I know it so easy my brain is frozen...
f(-4)=4-2(-4)
f(-4)=4+8
f(-4)=12
you must be bored of me by now..haha!
did you mean "find f(-4)"? if you did, you plug in (-4) for x and you get that f(-4)=4-2(-4)=12
To find the value of f(-4) when f(x) = 4-2x, you need to substitute x = -4 into the given function.
So, let's plug in x = -4 into the function:
f(-4) = 4 - 2(-4)
Now, simplify the expression:
f(-4) = 4 + 8
f(-4) = 12
Therefore, the correct answer is f(-4) = 12, not -2.
