so exg
input is the numbers that will work so normally the range is all real numbers
make sure that you don't have any numbers that will make impossiblities exg
is the function is f(x)=3/x you can't use 0 for x because 3/0 is undifined and is impossible so
input is the numbers you put in
out put is what numbesr you get from the input exg
if function =f(x)+x+3 then
if input=3,5,6 then output is
(replaace 3,5,6 for x and solve)
output is 6,8,9
