[patrickamp]

A function is a computation that takes an input and creates an output.

2. took awhile got it. (got to learn how to read)
   a.4
   b.17
   c. 0

3. f(x)
   = x/4 -5
   Whew…gotta lot to learn:)

2 b. 17

2 c. 0

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

[dekruife]

1. Takes an input and provides and output
2. a. 4
   b. 17
   c. 0
3. f(x)= (x/4) - 5

[eaglemind]

1. A function is a mathematical calculation that returns an output from every input. That is, whatever it produces as outcome is determined by what is fed into the system.

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

[akos.maksa]

1. Functions do computations. For each input, they give an output.

• 4
• 17
• 0

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

[TokyoCrypto]

[hutch]

Functions

1. Describe what a function does in your own words
   A function accepts an input; performs some form of calculation on it; and returns an output from the result of that calculation.

2. Calculate the output of the following function
   a) 4
   b) 17
   c) 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
