First, if y varies as the square of x, that means:
y = kx2
Step-by-step explanation:
where k is the constant of proportionality. When thinking about change, I like to use subscripts to represent before and after. We will use a subscript of 1 to denote before (or the initial value of a variable) and a subscript of 2 to represent after (or the final value of a variable). So, y1 is the initial and y2 is the final. Also, x1 is the initial and x2 is the final. k does not change, so it doesn't get any subscripts. Thus, we can write two equations, because the above equation must hold before and after.
y1 = k(x1)2
y2 = k(x2)2
