GCSE Maths Practice: graphs-of-quadratic-functions

Question 5 of 10

Choose the correct quadratic equation given its vertex and opening direction.

\( \text{Which of these equations has vertex at } (1, -2) \text{ and opens downward?} \)

Select all correct options:

Identify the vertex, use vertex form, then choose negative a for downward opening.

Vertex form: \(y = a(x - h)^2 + k\). Downward opening requires \(a < 0\).
