Inverse function
The function $f_{N}\rightarrow_{N}$ is one to one and the sum of all intercepts of its graph is $10$, the sum of all the intercept of the graph of $y =f^{-1}(x) is:$ $A) 10$ $B) -10$ $C) \frac{1}{10}$ $D)$ Depends on $f$

inverse function
Q. Let f be a function from A to B. Let S and T be subsets of B. Show that a) f−1(S ∪ T ) = f−1(S) ∪ f−1(T ). b) f−1(S ∩ T ) = f−1(S) ∩ f−1(T ).
