Evaluate the polynomial function f(x)=3x2−2x+5 f(x) = 3x^2 - 2x + 5 at x=2 x = 2 .

Solution

To evaluate the polynomial function f(x)=3x2−2x+5 f(x) = 3x^2 - 2x + 5 at x=2 x = 2 : 1. Substitute x=2 x = 2 into the function: f(2)=3(2)2−2(2)+5=12−4+5=13. f(2) = 3(2)^2 - 2(2) + 5 = 12 - 4 + 5 = 13. Therefore, f(2)=13 f(2) = 13 . Solved on Solvelet with Basic AI Model
