To find: all the values of
Given Information:
Consider the function
Concept used:
In the set of real numbers, the square root function is only defined when the radicand is not negative.
Calculation:
Substitute
Observe that the square root value for the negative radicand is not a real number.
So, for
Therefore, for
Plot the graph to show the expression is not defined graphically also.
It is observed from the graph that there are no points plotted for the values of
Therefore, the algebraic expression and the graph is not defined at
