Question

the graph of a quadratic function is shown.

what is the vertex of the function?

(0, 2)
(2, 0)
(-1, 1)
(1, -1)

Explanation:

Identify the vertex from the graph

$$ \text{Vertex} = (h, k) = (-1, 1) $$

Verify the coordinates against the options

$$ (h, k) = (-1, 1) $$

Answer:

• (0, 2)
• (2, 0)
• (-1, 1) (Correct answer)
• (1, -1)
