Question

Identify the vertex and y-intercept of the graph of the function y = (x + 2)^2 − 3. Use the drop-down menus to show your answer.

Answer 1

Vertex: (-2, -3)
y intercept: 1

Explanation:

Answer 2

Vertex of the quadratic function y = (x - h)² + k is:

• point (h, k)

Given function:

• y = (x + 2)² − 3
• h = -2, k= -3

Its vertex is (-2, -3)

The y-intercept is the point with x = 0:

• y = (0 + 2)² − 3 = 4 - 3 = 1

The y-intercept is (0, 1)
