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

Question

anonymous · Answer

Do you mean $  \huge f(x) = (x-1)^2 + 4) $

anonymous · Answer

If you look at  $ \huge f(x) = (x-1)^2 + 4) $  you can tell where the vertex is located.

 $ \huge f(x) = (x-1)^2 + 4) $    The  1 in $ (x-1)^2 $ is the x and the + 4 is the y so the vertex is (1,4)

anonymous · Answer

It also is telling the parabola to shift to the right by 1 and go up by four so where the  1 is located is known as the horizontal shift  area and the 4 is in the vertical shift area.

What do you think is the domain and range?

anonymous · Answer

Is the domain all real numbers? And the range is y greater than or equal to 4?

@Nixy  a = -1

anonymous · Answer

I'm unsure as to whether the vertex is truly (1,4) or if it is (-1,4). For reference, the function is f(x)=-(x+1)^2 +4
