im not sure how to make the comments on the transformations, intercepts and shape.

Could you please help me? - March 12th 2010, 03:02 AMProve It
You can't make any comments at all unless you try substituting a few numbers first.

Describe what you think happens when you change these numbers... - March 12th 2010, 01:17 PMmr fantastic
I am concerned that this question and the other ones similar to it are part of a major assignment you have been given that counts towards your final grade. MHF olicy is to not knowingly help with such questions because they are meant to be your own work.

Thread closed (you can discuss the matter with me via pm if the situation happens to be different to what I think it is).
