The graph of the function is shown below:

a)

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

[tex](7,-1)[/tex]

b)

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

[tex]x=7[/tex]

C)

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

[tex]\text{dom}=(-\infty,\infty)[/tex]

d)

From the graph we notice that the range is:

[tex]\text{range}=\lbrack-1,\infty)[/tex]

e)

The graph is increasing in the interval:

[tex](-1,\infty)[/tex]

f)

The graph is decreasing in the interval:

[tex](-\infty,1)[/tex]
