Answer 2

is this for an exam?

Answer 3

I believe for the first part it would be -5 and something

Answer 4

No its not for an exam

Answer 5

Answer 10

Ohhhh ok thanks

Answer 11

I just need to figure out what to come up with on part B.)

Answer 12

For part 2 of the question, you don't need to give the actual equation of the curve, just a possible equation based on the zeroes you found in part 1. (By the way, I think -5 and 4 are the ones with "possible multiplicities", since the shapes when they intersect are a parabola and a cubed function, respectively. I could be off base with this conclusion)

So, with the zeroes -5, -1, 4, 7, assuming -5 has multiplicity of 2 and 4 has multiplicity of 3, one possible equation could be:
(x+5) * (x+5) * (x+1) * (x-4) * (x-4) * (x-4) * (x-7)

This would also result in a seventh-degree polynomial, as the problem describes since 7 terms are multiplied together.
I think this is what the question is getting at, but to be honest, I'm guessing a bit on some parts

Answer 13

I think 4 has a multiplicity of 3, based on the shape of the curve near that point, but I could be mistaken about that

Answer 14

Omg yes thats what i was thinking

Answer 15

So 4 has a multiplicity of

Answer 16

3

Answer 17

Which one would be a better one for part B.) (x+5)^2(x+1)(x+2)(x-4)(x-7) or -(x-4)^3*(x+5)^2*(x+1)*(x-7)

Answer 18

Sorry for the late response

I think I would go with the second option, -(x-4)^3*(x+5)^2*(x+1)*(x-7)
The formatting is a bit neater and it shows the proper multiplicity of 4 and -5

Answer 19

Ok even putting "*" in between it?

Answer 20

Yeah, you can use the asterisk * to signify multiplication so that's fine to include

Answer 21

Ok thanks :)
