Question

If f(6) if f(x)=x^2 / 3 + x

Answer 1

f(6) = 4

Explanation:

We have given a function.

f(x) = x² / 3+x

We have to find the value of function when x is 6.

f(6) = ?

Now, putting x = 6 in given function , we have

f(6) = (6)² / 3+6

f(6) = 36 / 9

f(6) = 4 which is the answer.

Answer 2

1) If the function is
`f(x)=(x^(2))/((3+x))`,
`f(6)=4`

2) If the function is
`f(x)=x^((2/3))+x`,
`f(6)=9.30`

3) If the function is
`f(x)=(x^(2))/(3)+x`,
`f(6)=18`

Explanation:

To solve this problem you must apply the proccedure shown below:

f(6) means that you must substitute x=6 into the function above.

1. If the given the function
`f(x)=(x^(2))/((3+x))`, you obtain:

`f(6)=(6^(2))/((3+6))=4`

2. If the function is
`f(x)=x^((2/3))+x`

Then:

`f(6)=6^((2/3))+6=9.30`

3. If the function is
`f(x)=(x^(2))/(3)+x`

Then:

`f(6)=(6^(2))/(3)+6=18`
