Question

Which statement best describes the graph of -x3 - x2 + 4x + 4?

It starts down on the left and goes up on the right and intersects the x-axis at x = -2, 2, and 4.

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

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

It starts up on the left and goes down on the right and intersects the x-axis at x = -2, 2, and 4.

Answer 1

@Michele_Laino Could you help?

Answer 2

x-intercept where the graph of the equation cross x-axis

Answer 3

I tried making a graph about this but i couldnt really find anything...

Answer 4

if the highest degree is an odd number
then
if leading coefficient is negative =right end will fall & left end will rise
if leading coefficient is positive then= right end will rise &left end will fall

Answer 5

Can I show you the graph I got?

Answer 6

sure!

Answer 7

ok let me put it on a png hold on

Answer 8

nice
so what are the points where graph cross the xx-axiss

Answer 9

-2,-1, and 2

Answer 10

yes right

Answer 11

So it starts up on the left

Answer 12

yes

Answer 13

So it would be C or D.,... I think it would be c

Answer 14

yes
you got the 3 x-intercept first thing is to cancel out A and C cuz they have different x-intercetp

Answer 15

Thank you so much!!!

Answer 16

my pleasure.
