To graph any function just randomly put different numeric values and plot them in graph.

For ex. f(x)= 2x+5  F(2)=9   F(5)=15  Plot them you will get an idea to plot graph.  Another ex. f(x)=sinx.  f(π/2)=1.  f(0)=0.  Plot these values and you will get the answer

Here's a quick overview of Venn Diagrams and some set notation, if you have any further questions feel free to ask :)

I need notes on Venn Diagrams please.
