Shown below is the graph of the function
f :R-{0}→ R defined by, f(x)=(9-x^2)/(9x-x^2 )
Based on the above function, two statements are given below - one labelled Assertion (A) and the other labelled Reason (R). Read the statements carefully and choose the option that correctly describes statements (A) and (R).
Assertion (A): The function f is not onto.
Reason (R): 3 ∈ R (co-domain of f) has no pre-image in the domain of f.
A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is not the correct explanation of A.
