Question 322400
<font face="Garamond" size="+2">


Set the function equal to each of the given range values and then solve the resulting single variable linear equation for *[tex \Large x].  The set of 4 values obtained will be the desired domain.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ -4x\ +\ 1\ =\ 0]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ \  \ \ \ \ -4x\ =\ -1]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x\ =\ \frac{1}{4}]


is your first domain value.  Just repeat the process three more times.
