If what you want is to see it on your graphing calculator, say x = y², then you have to work around the fact that your calculator is built to graph FUNCTIONS of the form y = something done to x. So you solve x = y² for y and get TWO equations, y = √x and y = -√x, and graph them both.

Sideways Parabola

Yes, a sideways parabola will have a y^2 term instead of the usual x^2 term for a vertical parabola. An example of a sideways parabola equation is x=y^2.

A parabola: y = x^2 --- u or n shaped
A sideways parabola: x = y^2 --- c or reverse c shaped
Note that x=y^2 is the inverse of y=x^2, meaning that to get from one to the other, you have to reflect one of them about the line y=x.

Sure, you just swap your x and y. You'll have two values of y for each value of x. The simple way is to find the value of x for each y, but you could also solve for y^2 (you'll have two roots), or if the parabola is shifted, solve the resulting quadratic equation for the two values of y.
The general form of the equation is (y-k)^2 = 4p(x-h), for a vertex at h,k and a focus at h+p, k. if the vertex is at the origin, it's just y^2=4px.

instead of y = x^2 try x = y^2 instead?
