Question

If f(x)=2x^6-x-5, then what is the remainder when f(x) is divided by x-2?

Answer 1

+ 121

Explanation:

A function f(x) divided by (x - h) has remainder f(h)

Given

f(x) = 2
`x^(6)` - x - 5 divided by (x - 2) then remainder is f(2), thus

f(2) = 2
`(2)^(6)` - 2 - 5 = 2(64) - 7 = 128 - 7 = 121
