What will be the output for the following inputs?

a) f(2) = 4

b) f(7) = 17

c) f(0) = 0

3. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.

1. Describe what a function does in your own words?
   A function performs a computation of an input returning an output.
2. Calculate the output of the following function
   a). f(2)={2^2 if 2 is even 2+10 if 2 is odd} =4
   b). f(7)={7^2 if 7 is even 7+10 if 7 is odd} = 17
   c). f(0)={0^2 if 0 is even 0+10 if 0 is odd} =0

[cryptopunk]

a function does some tasks as computations. they may have an input and/or return an output value

calculations:
a) 4
b) 17

1. A Function is basically a computation that takes input and gives an output according to computation.

2. a) 4 b)17 c) 0

3. f(x) = (x/4)-5

[GoBeeGo]

1. A function is a mathematical operation. If you give a input, the function calculate it and gives you an output.
2. condition 1: f(x)=(x^2), if x is even,
   condition 2: f(x)=(x+10), if x is odd.
   GIVEN: a) x=2
   b) x=7
   c) x=0
   since a) x=2 is even an number we will use condition 1 so the output will be
   f(2)=2^2,
   so the answer is = 4

and b) x=7, since 7 is an odd number we will use condition 2 so that the output will be
f(7)=7+10,
so the answer is = 17

     c) x=0,
        f(0)=0^2  so the answer is =0

3. f(x)=(x/4)-5
