# If f is a function from X to Y and I x and I y are the identity function from X to X and Y to Y, respectively, then f ∘ I x = _ _ _ _ _ and I y ∘ f = _ _ _ _ _ _ .

To determine

To fill:

If f is a function from X to Y and Ix and Iy are the identity functions from X to X and Y to Y, respectively, then fIx=_________ and Iyf=______.

Explanation

Given information:

The given statement is,

“If f is a function from X to Y and Ix and Iy are the identity functions from X to X and Y to Y, respectively, then fIx=_________ and Iyf=______ ”.

Since f:XY, and

Ix:XX such that Ix(x)=x xXIy:YY such that Iy(y)=y yY

So
