Domain =

Range =

#### Explanation:

To find the x-intercept let

To find the y-intercept, let

Then draw the basic shape of the square root graph and deduce the domain (all possible allowed x-values as inputs) and the range (all possible allowed y-values as outputs).

graph{sqrt(4x-1) [-1.81, 10.68, -0.89, 5.353]}
