Question

Write an equation for the parabola with vertex at the origin.
Through (8, 7), opening to the right

Answer 1

\[y = 7/64x ^{2}\]

Answer 2

Solve this using \[y = a(x-h)^{2} + k\]
h and k are the x and y components of the vertex respectively. In this case, both are 0, resulting in \[y = ax ^{2}\] plug in the values of the point and solve for 'a' and you got your answer.
