# What is the domain of f(x)=.5x-1/3?

Oct 13, 2015

$\mathbb{R}$
All real numbers are allowed as inputs to this function so the domain is all real numbers $\mathbb{R}$.
As evidence hereof, see the graph of the function which is a straight line of gradient 0.5 and y-intercept -1/3 and hence stretches across all real numbers on the x-axis form $- \infty$ to $\infty$
