The polynomial 3x2 is a monomial with a degree of 2 .

The polynomial x2y + 3xy2 + 1 is a trinomial  with a degree of 3.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer: the answer is ann
