If: y+15 = 11 Then: y = -4
You can set this problem up like this: 48/4 = y/11 Cross multiply 48*11 = 4y 528 = 4y 528 divided by 4 = 132 So when w equals 11 y equals 132
Y=X^2 is a function for it forms a parabola on a graph.
y=11
determine whether each relation is a function y equals -8
y = x This is a line and a function. Function values are y values.

The vertex is (5, 11).
If: y+15 = 11 Then: y = -4
6-y equals 17x = -11
You can set this problem up like this: 48/4 = y/11 Cross multiply 48*11 = 4y 528 = 4y 528 divided by 4 = 132 So when w equals 11 y equals 132
If you plug in y for the x function, and it equals the answer you got, it is right.
y - |x| is an expression, not a function.
Y=X^2 is a function for it forms a parabola on a graph.
y=11
