Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
we know that
A composite function is a function that depends on another function. A composite function is created when one function is substituted into another function
we have


Part 1) Determine f(g(x))
To find f(g(x)) substitute the function g(x) as the variable in function f(x)
so

Part 2) Determine g(f(x))
To find g(f(x)) substitute the function f(x) as the variable in function g(x)
so

For x=5


<u>Story Problem</u>
Mr. Bill Gates bought a house in Italy for
and a house in Canada for
. What is the total cost of the two houses?
we know that
The total cost is the sum of the cost each house
so

therefore
the answer is
The total cost is

When you're given a point and the slope of a line, it is often easiest to write its equation in
point-slope form.
This is

, where

is the ordered pair for the point you are given and m is the slope.
Here, you would write

. Then, you simplify to get to
slope-intercept form, which is

, where b is the y-intercept.
The correct answer is A.
No derivation at x=3 .
only at x=3
