Question

HELP PLEASE!

Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
•g(x) = x3 − x2 − 4x + 4
•g(x) = x3 + 2x2 − 9x − 18
•g(x) = x3 − 3x2 − 4x + 12
•g(x) = x3 + 2x2 − 25x − 50
•g(x) = 2x3 + 14x2 − 2x − 14

Answer 1

help @ganeshie8

Answer 2

which one do you want to use?

Answer 3

the first one

Answer 4

ok now first thing we do is graph it

Answer 5

alright

Answer 6

Answer 7

this is how it looks

Answer 8

so we need to find
\(\Large\bf{~End~Behavior: \\ ~Y-Intercept(s): \\ ~Zeros:}\)

Answer 9

so what is it's end behavior?

Answer 10

@Cgsmith ?

Answer 11

That's what I'm still trying to figure out @Mehek14

Answer 12

is it going up or down in the end?

Answer 13

most likely it would end going up @Mehek14

Answer 14

correct
now where's the y-intercept?

Answer 15

I think it would either land on 5 or 4 @Mehek14

Answer 16

4

Answer 17

and zeros = x - intercepts:
x = -2
x = 1
x = 2

Answer 18

thank you so much..... I wish I could give you 2 medals @Mehek14
