Question

Find f(6) if f(x) = x2 ÷ 3 + x. 4 10 18

Answer 1

18 is the answer got it from the answer key

Answer 2

The value of f(6) is 18.

Explanation:

Given expression,

`f(x)=(x^2)/(3)+x-----(1)`

For finding the value of f(6),

Put x = 6 in equation (1),

`f(6)=(6^2)/(3)+6`

`=(36)/(3)+6`

`=12+6`

`=18`

Hence, the value of f(6) is 18 for the given expression.
