How do I graph these two problems?
y = −x2
g(x)= sqrt x-1
y = −x2
g(x)= sqrt x-1

a good place to start would be here. Does your text not have any examples of graphing functions?

A quadratic function
Graph the function g(x) = 4 − x2, and state the domain and range.
Solution
We plot enough points to get the correct shape of the graph.
See Fig. 11.10 for the graph. The domain is (−‡, ‡). From the graph we see that the largest y-coordinate is 4. So the range is (−‡, 4].
I can't paste the graph.
