Question

Based on the polynomial remainder theorem, what is the value of the function when x=−5?

f(x)=x^4+12x^3+30x^2−12x+70

Answer 1

5.

Explanation:

f(x)=x^4+12x^3+30x^2−12x+70

The remainder theorem says that f(a) is the value of f(x) when f(x) is divided by (x - a).

So when a = -5 f(a) will be 5.

Answer is 5.
