Question

There are multiple parts to this and the rest will be revealed upon answering the previous question correctly.Part A: what is the vertex?

Answer 1

The graph of the function is shown below:

a)

From the graph we notice that the vertex of the function is at the point:

`(7,-1)`

b)

From the graph we notice that the axis of the function is the line:

`x=7`

C)

Since this is a polynomial its domain is all the real numbers, that is:

`\text{dom}=(-\infty,\infty)`

d)

From the graph we notice that the range is:

`\text{range}=\lbrack-1,\infty)`

e)

The graph is increasing in the interval:

`(-1,\infty)`

f)

The graph is decreasing in the interval:

`(-\infty,1)`
