Q:
# for the function f(x) = -2(x + 3)^2 - 1, identify the vertex, domain, and range.β

Accepted Solution

A:

Answer:vertex (-3 , - 1)domain : all real number range: y <= -1Step-by-step explanation:y = a(x-h)^2 + k where vertex (h, k)In this casef(x) = -2(x + 3)^2 - 1 , h = - 3 and k = -1So vertex (-3 , - 1)Since a = - 2<0, the function is downward and Β has maximum = -1So Domain : all real number and range: y <= -1
