<h2>Answer with explanation:</h2>

We know that the general equation of a parabola in vertex form is given by:

y=a(x-h)^2+k

where the vertex of the parabola is at (h,k)

and if a>0 then the parabola is open upward and if a<0 then the parabola is open downward.

a)

f(x)=-2(x+3)^2-1

Since, the leading coefficient is negative.

Hence, the graph of the function is a parabola which is downward open.

The vertex of the function is at (-3,-1)

b)

f(x)=-2(x+3)^2+1

Again the leading coefficient is negative.

Hence, graph is open downward.

The vertex of the function is at (-3,1)

c)

f(x)=2(x+3)^2+1

The leading coefficient is positive.

Hence, graph is open upward.

The vertex of the function is at (-3,1)

d)

f(x)=2(x-3)^2+1

The leading coefficient is positive.

Hence, graph is open upward.

The vertex of the function is at (3,1)

That makes no sense I think you’re missing some words but the answer might be $7.5 per hour bc 21-6 is 15 and that divided by 2 s 7.5
