Write the eq of the parabola w/ vertex at the origin that satisfies the given conditions: a. The focus is on the x-axis and the parabola passes through the point (3,4) b. The parabola opens to the left and passes through the point (-3,4)

If the parabola passes through the origin, has the form $\displaystyle y^2=4px $. Evaluating at the given point, you can find p and the equation of the parabola.
Wait, to be honest, I really don't know how to do that, do I just have to plug in 3, 4 as x and y's at y2=4px?
Yep.
If that's the case, I'll get: 16=4(p)(3) p=12-16 p=-4 ....Lol, Correct me if I'm wrong.
