Question

Polynomials value 2x3-13x2+17x+100 when x=-5

Answer 1

The value of the polynomial f(x) = 2x^3 -13x^2 + 17x +100 at x = -5:

f(x) = 2x^3 -13x^2 + 17x +100

At x = -5,

f(-5) = 2(-5)^3 -13(-5)^2 + 17(-5) +100

= -250 + 325 - 85 + 100

= 425 - 335

= 90

Therefore, the correct answer is 90.
