Which point gives the vertex of f(x) = -x2 + 4x - 3? A) (2,-1)
B) (2.1)
C) (2,-13)
D) (-2,-13)

B

Step-by-step explanation:

There are several ways to find the vertex of function such as formula, completing the square or differential.

I will use the formula to find the vertex.

We are given the function:

Vertex Formula

Let (h,k) = vertex

From the function, compare the coefficients:

Therefore:-

Then evaluate for h-value and k-value.

Therefore the vertex is (h,k) = (2,1)

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
