Finish the steps below to write a quadratic
function for the parabola shown.
(6,5
1. Use the vertex form, f(x) = a(x - )2 + k,
and substitute in the values for h and k.
f(x) = a (x - 5)2 + 3
2. Use another point and substitute in values
for x and f(x). Solve for a.
5 = a(6-5)2 + 3
3. Write the function, using the values for h, k,
and a
NO
Vertex:
(5,3)
The function is f(x) =
