Question

Use substitution to determine whether 4 is a zero of the following. f(x)=x^(3)-9x^(2)+11x+33

Answer 1

Explanation:

To determine whether 4 is a zero of the given polynomial function f(x), we can use the substitution x = 4 to find:

f(4) = 4^3 - 9 * 4^2 + 11 * 4 + 33 = 262

Since 262 is not equal to 0, 4 is not a zero of the polynomial f(x) = x^3 - 9x^2 + 11x + 33. This means that 4 does not appear as a factor of the polynomial and is therefore not a zero of f(x).
