Question

if f (x) =2x²+3x²-11x+6 find the value of f(2)

Answer 1

8+12-22+6 =4 .... .................

Answer 2

Given function is
F(x) = 2x^2+3x^2-11x+6.
= 5x^2-11x+6.
Thus f(x) = 5x^2-11x+6.

Substituting x=2 in the function
We get
f(2) = 5(2.2)-11(2)+6.
= 5(4)-22+6.
=20-22+6
=4.

F(2)=4.


Hope this helps.
