Question

Which of the following are possible rational roots of the polynomial function?

Answer 1

Answer:  "possible" rational roots: ±1/5, ±3, ±1

Step-by-step explanation:  Take plus or minus the factors of the constant divided by the factors of the leading coefficient.

In this case, the constant is 3, so the factors are 1 and 3, and the leading coefficient is 5, so the factors are 5 and 1.

1/5, 3/5, 1/1 and 3/1  are possibilities, simplify and attach the ± to each.
