Which polynomial is in standard form?
a) 8x − 2x4 + 3x3 + 4x5 + 9
b) 7x2 + 5x3 + 4x5 − 6x + 7
c) x3 + 2x5 − 3x2 − 4x + 3
d) x5 + 3x4 − 2x3 − 3x2 + 2

D)

Step-by-step explanation:

A polynomial in its standard form is when the terms are arranged in descending order of exponent. The highest exponent goes first and smallest goes to the end of the polynomial.

The only one of the polynomials in the options that meets the requirements is D. Because the term with exponent 5 is at the beginning, then the term with exponent 4, and so on until the independent term.

The answer is: D)
