ib elite tutor explained functions
then it means that we can input any natural number for x here.
if x=1 then F(x) or y=1+5=6 similarly we can find much output just by changing values of x.
the combination of values of x and y like (x,y)= (1,6) is called an ordered pair. this helps us to draw the graph of the function. A function can have many inputs for a sing input like
It’s ordered pairs will be like (1,5),(2,5),(3,5),(4,5),…….all these are with a single output for multiple inputs. But a function can never have more than one output for a single input. ordered pairs like (1,5),(1,6),(1,7)…..are never possible for a function
