The first quadratic equation was not one-one , it was many one function.
I think there is mistake somewhere
I rechecked by all the three methods and its says that it is many one function

Even the parabola cuts the x-axis at two points
2nd ,Even the 1st order derivative is giving the positive as well as negative values , in your previous lectures u have said that if the 1st order derivative gives postive as well as negative value then it is a many one function

can u explain properly how to identify if the function is onto and one one etc
i know normaly but when i solved the sums which u were solving you said that we should i dentify in the sum first ?
so the examples which u gave
1)linear
2)rational
3) quadratic
how to identify in these questions which type of function it is one one onto etc etc??

Have you seen my lesson on one one onto ? Or u directly started with lesson..have gone through all the lessons of domain and range as well because that forms the fundamentals of inverse
