The graph of a quadratic function has a vertex located at (7,-3) and passes through points (5,5) and (9,5). which equation best represents this function?
a) f(x)=(x-7)^2-3
b) f(x)=2(x-7)^2-3
c) f(x)= -(x-5)^2+5
d) f(x)= -2(x-5)^2+5

B) .

Step-by-step explanation:

The vertex form of the equation is given by .

We plug in the vertex to obtain:

.

Since the graph passes through (5,5) and (9,5), they must satisfy its equation.

.

.

Divide both sides by 4.

Therefore the equation is:

.

what statement? is there an image?

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
