Question

Let X = {2, 3} and Y = {1,3,5} . How many different functions are there from X into y?

Answer 1

SOLUTION

GIVEN

Let X = {2, 3} and Y = {1,3,5}

TO DETERMINE

The number different functions are there from X into Y

EVALUATION

Here it is given that X = {2, 3} and Y = {1,3,5}

∴ n(X) = 2 & n(Y) = 3

Hence the number different functions are there from X into Y

$= \sf{ {3}^{2} }$

$\sf{ = 9}$
