Question

Based on the polynomial remainder theorem, what is the value of the function when

x = 3?

f(x)= x^4 – 2x^3 + 5x^2 – 7x + 4
Enter your answer in the box.
=f(3)

Answer 1

55

Explanation:

Value when x = 3

=> x⁴ - 2x³ + 5x² - 7x + 4

=> (3)⁴ - 2(3)³ + 5(3)² - 7(3) + 4

=> 81 - 2(27) + 5(9) - 21 + 4

=> 81 - 54 + 45 - 21 + 4

=> 130 - 75

=> 55
