The function , where and are real constants describes
Neither one-one nor onto mapping
Find the mapping of the given function
Given,
Therefore is a quadratic equation
Now,
So it is upward parabola.
For one element in co-domain this is exactly two pre-image. .
Hence by the definition of onto map it is not onto.
Now let
If it is one one then will imply
Therefore, the function is not one-one
Hence, it is neither one-one mapping nor onto mapping.
Hence, the correct option is .
