Answer 13

Hello, Mallory,
What have you been able to do so far towards solving / answering these problems?
Where would you like to begin?

Answer 14

I've partially answered A and D, i have completed C.
i am clueless on B and i need some explaining on A and D.

Answer 15

Try phrasing a question or two regarding A. What do you need to know to proceed further?

Answer 16

I see that it says increasing intervals, so as seen in the picture i took for you all i chose the 2nd, 3rd and 4th option. But i believe that the first option including infinity and -9 is also an increasing interval?? yes?

Answer 17

* (-infinity, -9) increasing interval, or not? i am lost

Answer 18

Not increasing intervals, Mal, but "intervals on which the function f(x) is increasing." Intervals don't increase or decrease, although numbers within them do or don't.

Look for the sections of the graph on which the functin is increasing.
Try again to list them.

Answer 19

So it should only be (-9,-7), (-3,1) and (4,7).

Answer 20

Yes. You're doing fine. What next?

Answer 21

B, does it mean exactly what it says? the X coordinate for the points in which the graph shows that they're low? So theres 3 points on this graph where they are minimas, correct?

Answer 22

-9, -3 and 4.

Answer 23

Not low, but lowest, that is, minimum points. Yes, there are 3 such points. Yes, they are -9, -3 and 4.

Answer 24

Next?

Answer 25

I've decided that from what my teacher has told me that the sign of the leading coefficient for C is negative.
so therefore, D. I cant ever understand what D means.

Answer 26

Is this function even or odd? Wonderfing whether you can answer that.

Answer 27

points
