What do you mean, "What are the coordinates of the parabola"? There are an infinite number of ordered pairs on the parabola.

This is like the other question except first you need an an equation: \[2x^2=8\] \[2x^28=0\] \[y=2x^28\] Since you need to graph, this is a parabola which has been vertically stretched by a factor of 2, and then shifted down 8.

The reason we make the expression equal 0, and then replace 0 with y is because we want to know the value of x when y=0....because that would be an xintercept (solution)

It must open up since the a value is 2, which is positive.

Nope. The parabola is moving down by 8, not 4.
