Question

How do you evaluate the function `f(x)=2` for f(-4)?

Answer 1

`f(-4)=2`

Explanation:

The function `f(x)=2` is simply a horizontal line with no slope. With that being said, for any input `x` the output will always be `2`. Therefore, `f(-4)=2`

Graphically, the line `y=2` is shown:

This shows that every `x` value will have the same `y` value
