Check whether the given function is in the form of y=kx or can be written in the form of y=kx.
Is x and y proportional? No. Explanation: The equation cannot be written as y=kx.
Practice makes perfect
We want to determine if x and y are proportional.
x^2=y ⇒ y=x^2
The given function cannot be written in the form of y= kx because of the 2 in the exponent. Therefore, we can say that x and y are not proportional.
