How do you solve this Exponential equation?: y = 4 x  (the "x" is placed as a square root).

I need help finding the points and other information, so that I can graph. I understand how to graph, im just struggling getting to that step, because I do not know how to even begin this problem.

We are asked to solve the exponential equation y = 4(x^1/2).

First we will divide both sides by 4.

=> y/4 =  (x^1/2)

Next, we will square both sides.

=> (y^2)/16 = x

=> (1/16) y^2 = x

The equation is (1/16) y^2 = xThis equation would graph as a parabola.
