# If f is a function from X to Y’,g is a function from Y to Z, and Y ⊆ Y , then g ∘ f is a function from _______to ___, and ( g ∘ f ) ( x ) = _ _ _ _ _ fro every x in X.

To determine

To fill:

If f is a function from X to Y, g is a function from Y to Z, and YY, then gf is a function from _____ to _____, and (gf)(x)=_____ for all x in X.

Explanation

Given information:

The given statement is,

“If f is a function from X to Y, g is a function from Y to Z, and YY, then gf is a function from _____ to _____, and (gf)(x)=_____ for all x in X ”.

Since, f:XY,g:YZ, so

(gf)(x)=g(f(x))=g(<
