Rob here on Functions:

1. In my own words, a function is a computation that takes direction or action. By defining the input, the output takes action.

2A.)

f(2) = 2^2
= 4

2B.)

f(7) = 7+10
= 17

2C.)  

f(0) = 0^0
= 0

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

[Sheree]

1. Describe what a function does in your own words
A function is a computation or formula which uses an input to deliver an output.

f(x) = {x^2 if x is even; x+10 if x is odd}

What will be the output for the following inputs?

a) f(2) x= 2 (2 is an even number, this means the formula x^2 applies.) 2^2 = 4
