The value of given function f(g(3) = 3. hence, correct option is B
What is a function?
- A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
- Originally, functions represented the idealized relationship between two changing quantities.
- In the past, the idea was developed with the infinitesimal calculus toward the end of the 17th century, and the functions that were taken into consideration were differentiable until the 19th century.
- The realms of application of the concept of a function were substantially expanded at the conclusion of the 19th century when it was defined in terms of set theory.
from the above we have
g(3) = 2
f (2) = 3
now putting the value, we have
f(g(3))=f(2)=3
