|Class 11 Maths Relation Functions||Function|
Function is a Set of action or activity.
E.g.: We can assume police as a function that will arrest a thief & lodge complain for a victim.
Consider function like a black box, if you give a input, it will give some output based on your input.
Function in mathematics world:
F(x) = x2
Note that 2 different input can have same output as well, eg for F(x) = x2 , both -5 & 5 gives output as 5.
But one input can’t have multiple outputs. E.g.: Input 3 will always give 9 in this case as output; it can’t give any other output.
