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)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
