Question

f(x)=12/(4x+2) Find f(-1).

Answer 1

@Loser66 I got 2 as my answer but it was wrong...

Answer 2

surely it is wrong :)
now, just replace -1 into the expression where you see x
\(f(\color{red}{x})=\dfrac{12}{4\color{red}{x}+2}\)
\(f(\color{red}{-1})=\dfrac{12}{4\color{red}{(-1)}+2}\)

Answer 3

what do you get?? redo, please

Answer 4

I got -f=-6

Answer 5

not -f, f(-1) = -6

Answer 6

Remember, call it by its name, don't touch the left hand side.

Answer 7

Oh right. You explained that earlier ;)
I can't believe I put 2 as my answer!
