f(x) = -4

#### Explanation:

A straight line which has a slope of 0 is a horizontal line.

Therefore the x value has no effect on the line at all,

The y value will always be -4.

In standard form :

This becomes

y =f(x). However this is not really a function of

The value of y will always be -4, regardless of which value of x is used.

f(x) = -4
