Question

Given f(x) = 6x4 – 10x3 + 40x – 50, find f(2). A) f(2) = 28 B) f(2) = 46 C) f(2) = 98 D) f(2) = 126

Answer 1

B) f(2) = 46

Explanation:

We are asked to find the function value at x = 2 so we substitute 2 wherever there is x in the function and evaluate

`f(x)=6x^(4) -10x^(3)+40x-50\\f(2)=6(2)^(4) -10(2)^(3)+40(2)-50\\f(2)=46`
