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.

Can you provide the intervals as coordinates with parenthesis? For example an interval of (-2,0)

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 ;)

Ohhh I see. Your answers r going by only x values. I thought your answers included y values in the intervals also.

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."

YOU 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.
