f(1) = 1
f(2)= 2

f(3) =

f(3) = 3

Step-by-step explanation:

(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

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
