Hey All

Got a test tomorrow, I'd appreciate some help. I'm pretty good in math but I just don't get these questions here.

Find, in the form y = ax2 + bx + c, the equation of the quadratic whose graph:

q1) touches the x-axis at 4 and passes through (2,12)

q2) has vertex (-4, 1) and passes through (1, 11)

You need to have 2 equations for the 2 different situations. It's the same technique but I just don't know it. Any help appreciated!!
