Question

What is the answer if f(x) = 2x-4 if f(x)= -2

Answer 1

Answer:

x = 1

Step-by-step explanation:

Since we know f(x) = -2, we can replace f(x) with -2 in our function and then solve for x:

$-2 = 2x -4$

Let's add 4 to both sides.

$2 = 2x$

And then divide both sides by 2.

$x=1$

And that's value of x, or the answer to our equation. Hopefully this was helpful... if you have more questions, let me know! :)
