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:
[tex]-2 = 2x -4[/tex]
Let's add 4 to both sides.
[tex]2 = 2x[/tex]
And then divide both sides by 2.
[tex]x=1[/tex]
And that's value of x, or the answer to our equation. Hopefully this was helpful... if you have more questions, let me know! :)
