Question

is f(x)=|sinx| one one ,if not one one function then plz explain why it is not one one

Answer 1

| sinx | is not one to one function

Reason :-

As we know one to one function gives specific value on specific input.

If we put 90° at x then we'll get output 1

But if we put 180° at x then also we'll get 1 as modulus function will invert -1 to 1 .

The condition of being 1 to 1 is broken here and hence the | sinx| is not one to one.
