Write the equation of the parabola in vertex form. The vertex is (β3, β4) and the parabola passes through the point (β1, 0).
Start with vertex form.
y = a(x β h)^2 + k
Using the vertex (β3, β4), substitute h = β3 and k = β4.
y = a(x β (β3))^2 + (β4)
y = a(x + 3)^2 + (β4)
Substitute the included point (β1, 0) into the equation for x and y.
0 = a(β1 + 3)^2 β 4
Simplify the equation to solve for a.
0 = a(2)^2 β 4
Type your answer and then click or tap Done.
Complete the equation for the parabola in the graph.
