Question #83615

Answer 1

`f(3)=4`

Explanation:

To evaluate a function `f(x)` at a given point `a`, we substitute in `a` wherever `x` is in the function.

The absolute value of any real number is the distance of that number from `0` on the number line. That is, `|x|=x` if `x>=0` and `|x|=-x` if `x<0`

With these in mind:

`f(3)=|(3)-5|+2`

`=|-2|+2`

`=2+2`

`=4`
