Question

Identify the vertex of the function below.f(x) - 4= (x + 1)2-onSelect one:O a. (-4,1)O b.(1,-4)O c. (-1,-4)O d.(-1,4)

Answer 1

The standard equation of a vertex is given by:

`f(x)=a(x-h)^2+k`

where (h,k) is the vertex.

Comparing with the given equation after re-arranging:

`f(x)=(x+1)^2+4`

The vertex of the function is (-1, 4)
