Question

Given the functions j(x) = x2 - 9 and k(x) = -x2 + 7x - 1, which operation results in a 3rd degree polynomial?

Answer 1

Do you have a list of choices or operations for the answer?
(j+k)(x) is first degree
(j*k)(x) is 4th degree
(j-k)(x) is second degree
(jok)(x) is fourth degree as well.
(j^(-1)) is not a polynomial.

Answer 2

Sorry I was having issues replying. The options are: addition, sub, mult, or no operation

Answer 3

So there are no operations for this problem?

Answer 4

Sorry, no, none of addition, subtraction and multiplication will give results in 3rd degree polynomial.
Hope that helps!

Answer 5

Yes it does! Thank you! Thank you! Thank you!

Answer 6
