Given the following functions:
f(x)=x2
g(x)=x−3
find the composition of the two functions and show your process:
f(g(x))
*** caution: this is different from
g(f(x))
2. given the following functions:
f(x)=x2
g(x)=x−3
find the composition of the two functions and show your process:
g(f(x))
caution: this is different from
f(g(x))
3. if the composition of two functions is:
1x−3
what would be the domain restriction? describe how you found that answer.

1) and are not equal
ie,
2) The domain is x
Step-by-step explanation:
Given functions are and
now find the composition of two functions verify that
now find the composition of
now find the composition of
Comparing the above two compositions we get
and are not equal
ie, .
2) Given that the composition of two function is x-3
Let the functons be f(x) and g(x)
so the composition of two function
it may be written as

Step-by-step explanation:
Let the age of Seema = P years old
1 / 4 of the age of Seema = 1 / 4 P years old
Seema's little sister = 5 years old
Seema's little sister
= ( 2 + 1 / 4 P ) years old
Equation ==>
2 + 1 / 4 P = 5
1 / 4 P = 5 - 2
1 / 4 P = 3
P = 3 ÷ 1 / 4
P = 3 × 4
P = 12
Seema is years old.
= P
= 12 years old
