Finish the steps below to write a quadratic function for the parabola shown.
11
Use the vertex form, f(x) = a(x - h)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 fx). Solve for a.
5 = a(6 - 5)2 + 3
3. Write the function, using the values for h, k,
and a
The function is f2) =
