Question:
Make the given changes in the indicated examples of this section and then plot the graphs.
In Example 5, change the + sign to −.
Data from Example 5
Graph the function
When finding the points for the graph, we may not let x take on any value less than −1, for all such values would lead to imaginary values for y and are not in the domain. Also, because we have the positive square root indicated, the range consists of all values of y that are positive or zero (y ≥ 0). See Fig. 3.19. Note that the graph starts at (−1, 0).
