4:33 but isme to even values nhi aa rhe hai how is it onto?

[@infamix5069]

there are numbers between also as it is real numbers so if u put X value any fraction u will get numbers between or any other number u will get even also. Simply the function should have both positive and negative values then there are all values between them too i hope its clear
