I realllllly don't understand how you work out the range of a function, i would reallly appreciate it if anyone could explain it for me simply please!
eg. state the range of g(x) = 2x^2 - 3
x Turn on thread page Beta
C3 Range?!? watch

okay, the range is the possible values of y for those in the domain (which tells you the values of x). The best way is to find the values of the minimum/maximum. Then the range is all the values of above/below/between the points depending what's what.
Hope that helps

OK, do you know what:
The shape of the graph is?
The lowest/highest possible value of g(x) is?

The graph is a positive x^2 curve, and thats all I'm saying. You should be able to sketch graphs and find lowest points by C3
