Question

For the function f(x) = –2(x + 3)2 − 1, identify the vertex, domain, and range.

Answer 1

The vertex is (–3, –1), the domain is all real numbers, and the range is y ≤ –1.

Answer 2

f(x) = -2(x + 3)^2 - 1
vertex = (-3, -1)
domain is all real number values of x and
range is all real numbers values of y less than or equal to -1.
