For f(x)  = x2+1 and g(x) = x2,find the composition fg and gf and identify the domain of each.Note: Domain of a function means those values of x at which both compositionare not undefined.

IDEA SOLUTION ATTACHED

Attachments:

Given f(χ) = χ²+1

g(χ) = χ-²

f∘g = (f∘g) (χ) = f(g(χ))

Putting values

=f(√χ-2)

=(√χ-2)²+1

=χ-2+1

=χ-1

Domain= (-∞,∞)

g∘f = (g∘f) (χ)

g = g(f(χ))

= g(χ²+1)

= √(χ²+1) - 2

= √(χ²-1)

Domain = (-∞,-1] , ∪ [1,∞)

thankssss Alot,,,
