1. Describe what a function does in your own words

A function takes an input, then provides an output based on that input which can change the information within the computation body of the function or output the same information without any change.

• a) f(2) = 4
• b) f(7) = 17
• c) f(0) = 0

f(x) = { (x/4) - 5}

   b). 17
   c). 0
3. f(x)= x/4 - 5

[Marcelo]

1. It operates like a computer receiving an input and giving an output by applying to the input some parameters.

2. The output will be X exponentially multiplied by 2 (square) if X is even.
   If X is odd, then it will be add to 10.
   a. 4
   b. 17
   c. 0

F(x) =
{
(x / 4) - 5
}

[Carl_The_Yoda]

1. Describe what a function does in your own words.
A function indicates to the program that a task is about to be performed. The elements of the function assign a value to the input which determines the mathematical output.

2. Calculate the output of the following function.

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) 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.

f(x) = {x/4}
f-5 = {}
f(x)=(x/4)-5

[Paval25]

1. A function is a math expression that transforms a set of given inputs into an output value.
2. a) 4, b) 17, c) 0
3. f(x) = x/4 - 5

[mkhuang]

1. Describe what a function does in your own words
   Function is a mathematical formula where a variable input will result in a output

2. What will be the output for the following inputs?
   • a) f(2) = 2^2 = 4

• b) f(7) = 7+10=17

• c) f(0) = 0^2=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.

F(x) = x/4 - 5

[UFAME]

1. A function is computation having input and output

2. Output shall be the input to the 2nd power if input is an even number, Output shall be the input plus 10 if the input is an odd number
   so,
   a) 4
   b) 17
   c) 0

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

[baads]

1. Describe what a function does in your own words

A function produces a output by inserting a variable input with a set of instructions on how to mathematically solve it.

2. Calculate the output of the following function
   f(2)=4
   f(7)=17
   f(0)=0

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

1. A function is a computation that transforms any relevant input, through the application of a specific calculation (aka algorithm) upon it, into a mathematically defined output.

2. f(x)
   a. f(2) = 4
   b. f(7) = 17
   c. f(0) = 0

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

[Josh_Siv]

1. A function is a input/output computation.

2. f(4)

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

[Ozarkshrub]

Here it comes baby! Time to kick the gray matter into gear.

1. Functions are how to run calculations, forming the base of algorithm.

2. f(x) = {x^2 if x is even, x+10 if x is odd}
   a. x=2 then 2^2=4
   b. x=7 then 7+10=17
   c. x=0 then 0^2=0

3. F(x) = {(x/4)-5}
