Question

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

The vertex is (–1, 4), the domain is all real numbers, and the range is y ≥ 4.
The vertex is (–1, 4), the domain is all real numbers, and the range is y ≤ 4.
The vertex is (1, 4), the domain is all real numbers, and the range is y ≥ 4.
The vertex is (1, 4), the domain is all real numbers, and the range is y ≤ 4.

Answer 1

can someone please help me quick

Answer 2

Yes sure x+1=0 implies x=-1 and at x=-1 y=4
so vertex is (-1,4)
f(x) = –(x + 1)^2 + 4<=4 so the range is y<=4
option b is correct
