Question

graph of a parabola has the following:
y-intercept at 60
minimum at (4.25, -12.25)
zero at 6

Find the other zero.

Answer 1

(0,60)
(60,0)
vertex along x = 4.25, axis of symmetry
vertex at (4.25,-12.25)

Sketch it.
The zero is 6-4.25 = 1.75 to the right of the axis of symmetry
Therefore the other zero is at 4.25 -1.75 = 2.5 so (2.5,0)

Answer 2
