Functions

Consider the functions
f(x)  = sqrt((x-7)/(x+3)) and g(x) = sqrt(x-7)/sqrt(x+3)
Explain why f and g are not the same function.


Good. You can read.

Re: Functions

Examine their domains (i.e. values for which each function is defined). Take, for example, x = −4. Is f and/or g defined at this value?
