Thank you. I now understand that “definition” in this context is synonymous with answer/solution.

[delaney]

1. A function is a computation that yields a specific output.
2. a) 4
   b) 17
   c) 0
3. f(x) = (x/4)- 5

[Eric_Roberts]

1. A function is a mathematical equation that converts a modifiable input (e.g. a single digit number) into an output by means of calculation (with said calculation being determined at the outset of the function’s creation).

a) f(2) = {4}

b) f(7) = {17}

c) f(0) = {0}

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

[Sanmal]

A function provides output to each unique input variable entered

a) 4
b) 17
c)0

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

[jerre]

1_ A function is a computation where a value is put through a formula and a unique output is produced.

2_ a) 4 b) 17 c) 0

3_ f(x)= {(x/4) -5}

[loudogg]

1. A function is a mathematical equation that takes an input, does a certain calculation with that input and creates an output.
2. a) 4
3. b) 17
4. c) 0

f(x) = {

(x÷4) - 5

}

[Ciantera_R]

1. A function is a generalized input-output process that defines a mapping of a set of input values to a set of output values.

2. f(2^2) => 4
   f(7) + 10 => 17
   f(0) => 0

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

[jctaylor9210]

1. is a computation for a problem based on an input and output

2. a. f(2) = 2^2 = 4
   b. f(7) = 7+10 = 17
   c. f(0) = 0^2 = 0

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

[liaoning]

1. Function represents a corresponding relationship in which each input value corresponds to a unique output value.
2. a) 4
   b)17
   c) 0
3. f(x)=x/4-5

[Mockchain]

1. A function is a formula or series of formulas where a given input can produce an output accordant to the formula(s) provided.

2a. 4
2b. 17
2c. 0

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

[tenbad]

1. Describe what a function does in your own words
   A: A function is an operation performed on a variable or variables, which once recorded will be performed each time the function is called.

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) Answer: 4
b) f(7) Answer: 17
c) f(0) Answer: 0

4. 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
   }

[VSapphire]

1. A function can be written several ways. It requires a name such as f for function. Written f(x)… It takes an input creates a relationship and gives you an output.

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

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

[Sluggo]

1. A function takes an input which is usually a number or even a variable, inserts it into mathematical instructions and produces an output.

2. f(2) = 4, which is 2 squared since 2 is an even number.
   f(7) = 17, since 7 is odd and 7 + 10 = 17.
   f(0) = 0 as zero is generally considered to be an even number.

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

[JJG2323]

1- a function is a computation that you give an input to and subsequently get an output
2.a- 4
b- 17
c- 0
3- f(x)= (x/4)-5

[Dawton]

1. A function is a computation from an input to get and output.

2. 4

   0

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