Question

How do you evaluate the function f(x) = 1/3x + 5 at x = 6?

Answer 1

`f(6) = 7`

Explanation:

Start with:
`f(x) = 1/3x + 5`

Substitute in the value x=6:
`f(6) = 1/3(6) +5`

Simplify
`f(6) = 2 + 5 = 7`

Hence:
`f(6) = 7`

Answer 2

See explanation.

Explanation:

To calculate the value of a function at the specified point you have to substitute the given value for any occurance of the unknown (usually `x`) in the function formula.

Here the variable is `x` and the value is `6`. The substitution is:

`f(color(red)(6))=1/3*color(red)(6)+5=2+5=7`
