This question really belongs in Calculus. This question is asking for the range of g. How do you normally go about finding the range?
I have this question, I don't quite know how to approach it :
g : R → R
I need to find Img(g) and determine if its one-to-one function.
then it asks - what will happen to the image if we reduce the interval to [0,∞)
thanks in advance.
