Question

Which of the following polynomials is in standard form?

A. F(x) = 5x +2x3 – x2 - 3
B. F(x) = 2x3 - x2 +5x - 3
C. F(x) = -3 +5x-x2+2x3
D. F(x) = -3 - x2 + 2x3 +5x

Answer 1

B option

Explanation:

Standard form of a 3⁰ equation is,

f(x) = ax³ + bx² + cx + d

It matches with option b, where, a = 2, b = -1, c = 5 & d = -3. Hence, the answer.

Hope it helps.
