Which of the following relations define y as a function of x? Explain why or why not for each.
A) y = 3x^2 + 4
y is a function of x because for each x value there is one y-value.
---------------
B) (2,6),(3,8),(2,-2),(-1,6)
y is not a function of x because when x=2 there are two different values for y.
---------------
C) y = |x|
y is a function of x.
---------------
D) x = y^2
y is not a function of x.
