Homework Help: Calculus

Posted by Chelsea on Tuesday, September 21, 2010 at 2:47pm.

Find expressions for the quadratic functions whose graphs are shown. One graph has the point (4,2) plotted in which the parabola passes through (U-shaped parabola- right side up) The vertex is at (3,0) and the parabola does not touch the y-axis for as much is shown.

So, I did this:

a(3)^2 + b(3) + c = 0
Solve: c = -12

For the point (4,2):
a(4)^2 + b(4) - 12 = 2
Solve: 16a + 4b = 14

I am not sure if I am doing this correctly and I am also stuck at the is point. Please help.
