#1**0 **

a. The positive parts are -6

b. The negative parts are -3

c.It is increasing at -8

d. decreasing at 4

e. The constant part is x<-6

f.The domain of the function is x<=13. The range of the function is -9<=y<=7.

#3**0 **

a. when x = (-6, -3) and (3,13)

b. when x = (\(-\infty\), -6) and (-3,3)

c. when x= (0,4) and (-8, -4)

d. when x = (4,13) and (-4,0)

e. when x =(\(-\infty\),-8)

f.the domain is when x = (\(-\infty \),13) and the range is when y = (-9,7)

So for e., would the graph be constant over the interval of (-∞, -7)? I thought maybe you made a mistake there ;)

Imheretosavetheday,

Guest has no idea what you are on about. Maybe s/he did eventually work it out but you did not explain.

You have not even tried to teach guest a solitary thing!

**Guest.**

The graph is positive when the y value is positive, I mean the graph must be above the x axis.

You could change the wording to : "For what values of x will the function (graph) be positive."

Y**OU only refer to the x values.**

so

since it is above the x axis (where y is positive) between -6 and -3 and then again for all values of x greater than +3

I can say

The graph is positve from (-6,-3) and (+3, +infinity)

You use ( or ) if the end point IS NOT included

and you use [ or ] if the end point IS included.
