Question

Identify the vertex and y intercept of g(x) = -3(x+2)² + 5. Please remember the parent function is f(x) = x² and graph the parent function and g(x) =-3(x+2)² + 5.

(2,-5) vertex ; y intercept is (0,-5)

(-2,-5) is vertex ; y-intercept is (0,-5)

(2,5 is vertex ; y-intercept (0,5)

(-2,5) is vertex ; y-intercept (0,5)

Answer 1

(-2,5) is vertex ; y-intercept (0,5) but the y-intercept is actually (0,-7).

Explanation:

Answer 2

(-2,5) is vertex ; y-intercept (0,5) but the y-intercept is actually (0,-7).

Explanation:

The vertex form of a quadratic is
`y=a(x-h)^2+k` where the vertex is (h,k). Here h=-2 and k=5. So the vertex is (-2,5).
