Homework on Functions - Questions

1. Describe what a function does in your own words
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)
• b) f(7)
• c) f(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. Function is our way of communicating with a computer/program using code to get desired action.

2. a) 4
   b) 17
   c) 0

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

[JJM]

A function is a mathematical construct that applies an alteration to a given input. The input thus gives an output altered by the equation defined in the function itself.

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

f(x) = x/4 - 5

[Alfonso]

1-Describe what a function does.

Answer: A function is a mathematical equation which define the values of a variable (X), you can say that it describe the behavior of such a variable.

[BKCryptoFNG]

A function is a mathematical procedure to get a desired result.
4,17,2
Function F takes input x then divides by 4, then subtracts by 5

[Crypto_Tax_Fixer]

Describe what a function does in your own words
A function is a mathematical formula applied to an input to generate a specific output.

Calculate the output of the following function. What will be the output for the following inputs?

a) f(2)=4

b) f(7)=17

c) f(0)=0

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

[Colin358]

1. Functions are mathematical formulas applied to inputs that generate an output.

2. a) 4
   b) 17
   c) 0

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

[LXSO]

1. A function is a mathematical operations and computer code that takes in an input and returns an output.

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

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

[shanemulv]

1A function is a mathematic formulae that takes an input applies the computational work and gives an output.
2 x=4
b x=17
c x=0
3*f(x)=(x/4)-5

[JonathanGroschel]

A function is a formula for how something should be calculated based on the input.

a)4
b)17
c)0

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

[Davide_Coltro]

1. With an input, a function does a computation and gives an output.
2. a) 4. b) 17. c) 0.
3. f(x) = (x/4) -5.

Describe what a function does in your own words

• A function accepts specific data that it is given, and returns a result.

Calculate the output of the following functions:

• F(2) = x^2 = 2^2 = 4
• F(7) = x+10 = 7+10 = 17
• F(0) = x^2 = 0^2 = 0

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

[cryptofreedom70]

1. Function - is a set of inputs to a set of possible outputs where each input is related to exactly one
   output.

2. f(2) = 4
   f(7) = 17
   f(0) = 0

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

Thanks a lot @SatoshiNoobamoto
Amazing that you want to help out other students.
I really appreciate it.
Have a nice day.

@247earnings

Not sure what ^ means.
?, 17, x

@CryptoRealNews

f(0) = 0 or (suspended or crash)

There is no crash in doing 0^2. It’s defined. (0)

[Fabrice]

@Sintrality

f(x) = x^2
f(2) = 4
f(7) = 49
f(0) = 0

f(x) = x+10
f(2) = 12
f(7) = 17
f(0) = 10

In this question you need todo (x+10) if x is odd
Or perform (x^2) if x is even.

[Fabrice]

@Matgas

4, 7, 0

7 is odd, so replace x by 7 = 7 + 10 = 17

[Fabrice]

@Crypto_and_beer

I disagree with all of you.
0 ^ 2 = 2.
What is your reference for the meaning of ^? (the caret)

@petr

0 is not even or odd. It’s condition for function.

The parity of zero is even

[Fabrice]

@ajphminer

c) no output

The parity of zero is even
0^2 = 0 (defined)
