If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
no
Y=X^2 is a function for it forms a parabola on a graph.
Yes, it is.
Yes.
determine whether each relation is a function y equals -8
y = x This is a line and a function. Function values are y values.
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
no
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.
Yes, it is.
Yes.
Yes.
3x1/5
Y=sin X is a function because for each value of X, there is exactly one Y value.
