Question

Which statement best describes the graph of x3 − 3x2 − x + 3?

It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 2, and 3.
It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 1, and 3.

Answer 1

when highest degree is odd
then if leading coefficient is positive
right side will rise , left end will fall
AND if leading coefficient is negative then right end will fall and left end will rise
so leading coefficient is negative or positive ?

Answer 2

postive?

Answer 3

yes right

Answer 4

are you allowed to graph it ? if yes then point where line cross x-axis is x-intercept

Answer 5

its just multiple choice so I have to pick an answer but i can try graphing it

Answer 6

okay
or you can substitute y for 0 to find x-intercept

Answer 7

so what's ur answer?

Answer 8

I got..... It starts up on the left and goes down on the right and intersects the x-axis at x = −1, 1, and 3.

Answer 9

but now I'm thinking its more like b

Answer 10

so which one ?
read what i posted above when leading coefficient is positive left side increase or decrease ?

Answer 11

Im think B is correct if I did my graph right

Answer 12

yes right

Answer 13

so b is correct?

Answer 14

graphing is good
but you don't really need after that info if leading coefficient is positive
then left side will fall and right side will rise

Answer 15

thank you!

Answer 16

my pleasure :=)
