How does the graph with a quadratic function with an x^2 term differ from the graph of the quadratic function with a y^2 term?

The graph of a quadratic function y = ax² is a VERTICAL parabola open upward or downward depending whether a (the coefficient of x) is positive or negative

The graph y² = ax or y = √ax is a HORIZONTAL parabola open to the right or to the left depending whether a (the coefficient of x) is positive or negative

Y^2=ax there is one more answer to this but I don't have the sign on my phone for it
