find equation for the parabola vertex (2,5) another point is (3,7) . would the a value be 1 or 1.4
We have this
y = a (x - h)2 + k where h, k = 2,5....and we know that (x,y) = (3, 7).is a point on the parabola.....so we have
7 = a(3 - 2)2 + 5 simplify
7 = a(1)2 + 5
2 = a
So...the equation is
y = 2(x - 2)2 + 5
