Question

Which of the following is a fourth degree polynomial function select all that apply (2 answers)

Answer 1

Step-by-step explanation:

Here, we want to get the functions which are fourth degree polynomials

A fourth degree polynomial will have the highest power as 4 in its expression

Let us take a look at the values one after the other:

a) This is not a fourth degree polynomial. It is a third degree polynomial. This is because the highest power we can see is 3

b) This is a fourth degree polynomial. This can be see with the power x^4

c) This is not a fourth degree polynomial. It is not because it has been divided. If it stood alone and not being a dividend to 1, then it would have being a fourth degree polynomial

d) This is a fourth degree polynomial since the highest power is 4

Conclusively, we can see that the second and last options are the fourth degree polynomials here
