im jst guessing thats its the 3rd choice? idk
the domain is all the possible values of x
domain is defined where the function is defined all for all x there exists a y so all x
so its the 3rd choice? i only said that bc it was the only one the red lime cut through
x can be 1 - the function is defined at 1 x can be 1000 , 5000 whatever ( real numbers)
all real numbers?
thank you !
