Question

How to find the exact range of composite function?

Answer 1

depends on the function

Answer 2

yeahh, it changes from function to function. and you can't predict the range OR the domain just by looking at the functions. you need to make the composite and then see.

Answer 3

f(gx)), well if your global maxima and minima are (a,b) and (c,d) respectively then ur range is [d,b]

Answer 4

U must therefor differentiate f of g and find (a,b) (c,d)
