Answer:
f(3) = 3
Step-by-step explanation:
f(1) = 1
f(2) = 2
f(n) = f(n − 2) + f(n − 1)
f(3) = f(3 - 2) + f(3 - 1)
= f(1) + f(2) = 1 + 2 = 3
Special Note: Have you heard of the Fibonacci sequence?
The formula f(n) = f(n − 2) + f(n − 1) is used to find the terms of the of the Fibonacci sequence
A) - 14 is the correct answer
Answer:

Step-by-step explanation:
<u>Composite Function
</u>
Given f(x) and h(x) real functions, the composite function named
is defined as:

It can be found by substituting h into f.
We are given the functions:


It's required to find 
As defined above:

Thus:

Find h(2):

h(2)=0
Now:


In this case of your exercise you need to know that
4^(1/2) = sqrt(4)
hope this help you
