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.

The correct option is 2.

Step-by-step explanation:

The given function is

                    ..... (1)

The standard form of a parabola is

                      .....(2)

Where, (h,k) is the vertex and a is stretch factor.

On comparing (1) and (2), we get

The vertex of the parabola is (-1,4). Since a=-1<0, therefore it is a downward parabola. Domain of an downward parabola is all real numbers.

The vertex of a downward parabola is the point of maxima. So the range of the function can not be more that 4.

Therefore  the domain is all real numbers, and the range is y ≤ 4. Option 2 is correct.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the equivalent expression are always the hardest ones but you look at the gcf also
