# What is the domain of f(x)=4?

Oct 7, 2014

The domain for this function is all real numbers, $\left(- \infty , \infty\right) .$ This a function is a constant function. No matter what input value is used the output value will be $4.$

$f \left(\pi\right) = 4$

$f \left(0\right) = 4$

$f \left(- 7\right) = 4$

$f \left(e\right) = 4$

$f \left(0.09\right) = 4$

$f \left(\frac{3}{4}\right) = 4$

$f \left(- \frac{1}{8}\right) = 4$
