Answer:
Step-by-step explanation:
Given polynomial is,
x - 1 + 2x³ - 3x⁴ + 5x⁵
2.1) Number of terms in the given polynomial = 5
2.2) Degree of polynomial = Highest exponent of polynomial = 5
2.3) Constant term of the given polynomial = 1
2.4) Polynomial in descending order,
5x⁵ - 3x⁴ + 2x³ + x - 1
2.5) Value of polynomial at x = -1
5(-1)⁵ - 3(-1)⁴ + 2(-1)³ + (-1) - 1 = -5 - 3 - 2 - 1 - 1
= -12
