Question

Find the domain of the function.

Answer 1

the domain is where the function gives values, when the denominator =0 than the fraction does not exist so 4x-1 cannot be equal to 0
4x-1=0
x=1/4
so the domain is all the real numbers except x=1/4

Answer 2

so what does that mean

Answer 3

does that mean (-inf,1/4)u(1/4,inf)

Answer 4

yes that is one way of writing it, but I prefer this:
\[ x \in \mathbb{R} \] \x=1/4

Answer 5

this should be one line, but I could not make it :-)
