Question

For the function f(x) = -(x + 1)^ 2 + 4, identify the vertex, domain, and range.

Answer 1

A.) The vertex is (-1, 4), the domain is all real numbers, and the range is y ≥ 4.
B.) The vertex is (-1, 4), the domain is all real numbers, and the range is y ≤ 4.
C.) The vertex is (1, 4), the domain is all real numbers, and the range is y ≥ 4.
D.) The vertex is (1, 4), the domain is all real numbers, and the range is y ≤ 4.

Answer 2

oh yea its dookey!!

Answer 3

Its A

Answer 4

Okay thank you(: but can you explain please?

Answer 5

Ok so concerning the vertex you shiuld find the derivative f'(x) and then equate it to 0

Answer 6

You are familiar with derivative yeah?
