Graph quadratic functions in vertex form

Identify quadratic functions in vertex form from their graphs and find key features of their graphs (intercepts, vertex, axis of symmetry) from the equation. Based on Common Cor...

What is the vertex of the graph of f(x) = 2(x + 3)² + 2?

(3, 2) (−3, 2) (3, −2) (−3, −2)
What is the y-intercept of the graph of f(x) = 2(x + 3)² + 2?

(0, 2) (0, 18) (0, 20) (0, 38)
What are the x-intercepts of the graph of f(x) = 2(x + 3)² + 2?

(0, 20) only (2, 0) and (4, 0) (−2, 0) and (−4, 0) There are no x-intercepts.
