The functions f and g are defined as follows:
f(x)=√x+1x−1andg(x)=√x+1√x−1. Explain why the functions f and g are not the same function.
(Sorry if the Latex isn't displaying properly.)
For the g function x must be greater than 1. Why is that?
Is this true for the f function? Can x be -3 (for example)
+185
