Finding the equation of a parabola

  1. Aug 24, 2012 #1
    1. The problem statement, all variables and given/known data
    Alright so I wasn't sure if I should put this in the Calculus section, but just in case that I would need derivatives to solve this I decided I would put this thread here.

    3. The attempt at a solution
    I tried finding the relationship with trigonometry but it didn't work because the parabola is curved and does not extend as a straight line like a triangle. Could anyone give me a hint on how to start this question?

    y=ax2+bx+c

    You have 2 points where the tangents are given and y intercept.
