Question

Algebra 1 help! Fan and medal!!

Answer 1

What do you need?

Answer 2

1. Esmeralda and Heinz are working to graph a polynomial function, f(x). Esmeralda says that the third-degree polynomial has four intercepts. Heinz argues that the function only crosses the x-axis three times. Is there a way for them both to be correct? Explain your answer.

Answer 3

That is the first question. There's 4

Answer 4

@ANA789 do you think you can help?

Answer 5

Please guys I need help!

Answer 6

@GeniousCreation please I beg of you, can you help me?

Answer 7

@mely1014 Im sorry Im not very good at equations like this

Answer 8

@ANA789 well do you know someone who can help me?

Answer 9

@Robert136

Answer 10

@xapproachesinfinity can you help??

Answer 11

actually no!
according to the fundamental theorem of algebra
a third degree if its solutions are all real then i will cross the x axis three times
if not then it will have at least one real solution
4 intercepts means 4 real solutions which is not true for a third degree polynomial

Answer 12

@xapproachesinfinity OK so I would put it like this-
No because a third degree has to have all real solutions for it to pass the x-axis three times.

Answer 13

@Flvs_student21 I used to go to flvs, think you can help me with the other questions?

Answer 14

I can try

Answer 15

2. Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to Heinz the other key features of g(x).
• 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
This is the second question

Answer 16

I found this this for you I am not this far in math yet but it is somebody helping someone else out with the problems and it made since to me I hope this helps I'm sorry I couldn't really help u

Answer 17

@wil476003 it helps in the first 3. Thank you! I still need the last one though but thanks

Answer 18

Yurp I'm sorry if I new it I would help you solve it all

Answer 19

@wil476003 this is more than enough. Thanks again:)

Answer 20

No that is not what i said!
i said that a third degree can have a maximum of 3 real solution it can't have more than that

Answer 21

@xapproachesinfinity calm down haha. It's what I understood
