Answer :
mathematical relationship in which each input corresponds to the same terms.
A function is a mathematical expression that describes the relation between each input and output . for example F(x) = x+2 In this equation F(x) is your output and x is your input .
If x=2 ; F(x) = 4 , If x= 3 ; F(x) = 5 .
If x=2 ; F(x) = 4 , If x= 3 ; F(x) = 5 .
