G(r)=−(r+11)(r+14)

1) what are the zeros of the function?

write the smaller r first, and the larger r second.

smaller

larger

2) what is the vertex of the parabola

The zeros are

Larger

Smaller

2)The vertex is (-12.5,-2.25)

Step-by-step explanation:

The given function is:

This function is already in the factored form therefore it is easy to find the zeros,

Either or

The zeros are or

b) The expanded form of the given function is:

We obtain the vertex form by completing the square:

The vertex form is:

Therefore the vertex is (-12.5,-2.25)

$32,660

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
