y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.

Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
          - 12 -12
2. 1/4(x) = -10  - 1/4  since its a fraction, you'll have to subtract not divide
-1/4    - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
