Hello
Another example is a parabola opening down with its summit below the x-axis
here : -x² + 2x - 2

f(x) = -5.
This is a constant function, where for each x value, the function evaluated at x is the number -5.
This is below the x-axis because -5 < 0.

it means that the value of function is always negative..
f(x)=k , where k < 0
others are
f(x)=log(x-[x]), where x is not an integer and [x] denotes greatest integer less than or equal to x.
or
f(x)=-e^x
