Since the given function is a rational function,the domain is the set of all real numbers except for the value of x that will make the denominator equal to zero. This gives us
In other words, the domain is the set of all real numbers except 4. When written in interval notation, the domain will be
`(-oo,4)uu(4,oo)`
Find the domain of the function:
`f(x)=1/(3x-12)`
The function is undefined for x values such as:
`3x-12=0`
`3x=12`
`x=12/3=4`
Thus the domain of the function is (-`oo`,4) and (4,`oo`)
