Question 6 of 10

Write the equation of a downward-opening quadratic given its vertex.

‹ ›

\( \text{Write the equation of a quadratic with vertex } (-2, 3) \text{ that opens downwards} \)

Choose one option:

Plug in h, k, a to get the equation in vertex form.

Vertex form: \(y = a(x - h)^2 + k\). Substitute h = -2, k = 3, a = -1 for downward opening.
