How do I solve (graph) functions which are a combination of 2 basic functions. More specifcally:
f(x)= 1/x^2?
Basically I am asking, how do I know which function I should be making the transformations to. (example. x^2-2 In this one I know that I would be making the transformations to a parabola.
I am also having trouble with this one:
f(x) = 1/x^2-x-6
-I think that it looks like a parabola but I am not sure because I don't know how the -x affects it.
Last problem. For reference-http://en.wikipedia.org/wiki/Functional_composition
g o f = h
f(x)=x+4 & h(x)= 3x^2+3x+2
I know how to do questions in which the known function is first but not when it's second.
Thanks for your help
