In Exercises 39-50, sketch the graph of the function with the given rule. Find the domain and range of the function.
To evaluate: The graph of the given function. Find the domain and range of the function.
The graph of function .
Find some points on the curve, join these points with the smooth curve to get the curve of given function.
Substitute different real values of for x and find the value of .
Table for different values of x and is shown below.
Plot these points on the coordinate axes and join them with a smooth curve as shown below.
The graph of function is shown in Figure (1).
Domain is the set of real values of independent variables for which function is real and defined.
The function is only defined when because square root of negative numbers is not defined.
Simplify the inequality
