Question

what is real value function?why composition and product of two function are same ?
f(g(x))=f(x).g(x)?why

xapproachesinfinity · Answer

A real valued function is a function that takes a real numbers as input and spits another real number for that input

xapproachesinfinity · Answer

your second question
the prodcutof two functions is not the same as the composition of two functions
that's a false statement

xapproachesinfinity · Answer

hence :
$$f(g(x))\neq f(x)g(x)$$

xapproachesinfinity · Answer

here is what the composition does
$$x \rightarrow f(x)\rightarrow g(f(x))$$
f(x) takes x and input and gives and output
then g takes that output and makes it its inputs to give a new output assigned by g(f(x))
see f(x) become the input there

hope you got this!

check this link of wikipedia http://en.wikipedia.org/wiki/Pointwise_product

xapproachesinfinity · Answer

that has nothing to do with the composition
+ that thing is very advanced things to look at
just focus on simple definitions now
