Write the equation of the parabola in vertex form if the vertex is (β1, 0) and the parabola passes through the point (β2, 2).
Start with the vertex form.
y = a(x β h)^2 + k
Using the vertex (β1, 0), substitute h = β1 and k = 0.
y = a(x β (β1))^2 + 0
y = a(x + 1)^2
Substitute the included point into the equation for x and y.
2 = a(β2 + 1)^2
Simplify the equation to solve for a.
2 = a(β1)^2
Type your answer and then click or tap Done.
Complete the equation for the parabola in the graph.
y = Fill in the blank text field 1
(x + 1)^2
