Answer:
14 = x
Step-by-step explanation:
-2 on both sides you get 7 = x/2, multiply both sides by 2 and you get 14 = x
Okay, so first you make f(x) = y and switch x and y. So the equation becomes:
x = y^2 - 16
The next step is to get y by itself. So first you add 16 to both sides:
x + 16 = y^2
Now you square root everything, so the final answer is going to be:
the square root of x + 4 = y
