If you have troubles to understand, I can always do a voice chat on discord or something.

@Jikkerman

) f(0) = 0 is neither odd nor even so~ I guess Error 404

The parity of zero is ‘even’
So 0^2=0

[Fabrice]

@Zado

f(x)= (:4) - 5

f(x) = x/4 - 5
So it divides the input(x) with 4 and this result minus 5

@bitcoinjim

I don’t remember its been many years.

You need to change x with the giving values. Then depending if x is even or odd you do a different operation.

f(2) so if you change x with 2 = even, so 2^2=4
b) f(7) = 7 is odd so we need to add 10 (7+10)= 17
c) f(0) = 0 is even so 0^2 = 0

@Toby_K

2 - 4
17
0

4 is the answer to a)
^ means a power relation so ^2 means multiply by itself.

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. a fonction is a process which perform calculus over data entries to produce a mathematical answer.

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

f(x)=x/4-5

1. A function is a math computation that takes an input and gets an output.

2a) f(2) = 4

2b) f(7) = 17

2c) f(0) = not defined

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

[Klemen]

1. Function takes input provided and follows it’s predefined procedure to give an output

2. • 4
   • 17
   • 0 or error lol?

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

[Suspect5]

1. Describe what a function does in your own words
   A function is a computation or equation in which there is a variable input which result in an output.

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

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

[Tayowulf]

1. A function is the action between an input and an output.

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

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

[Geydominic]

thanks for the graphic explication it clarify my mind

[Theo1997]

1. A function adds something to an input to give an output.

2. a) f(2) = 2^2 = 4
   b) f(7) = 7+10= 17
   c) f(0) = 0^0=1

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

[Geydominic]

1 Function is an instruction that activate an output giving a input.
2 a) f (2) if is even = 4
b) f (7) if is odd +10 = 17
c) f (0) not sure

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

[timtim]

1. Function is a computation which reaches a certain outcome (output) depending on the input.

2. a. 4
   b. 17
   c. 0

3. f(x) = x/4 – 5

[Fabrice]

@ajcapo90

2c) f(0) = not defined

The parity of zero is even, so 0^2=0 (0 x 0)

[Fabrice]

@Geydominic

c) f (0) not sure

The parity of zero is even, so 0^2=0 (0 x 0)

[Fabrice]

@Theo1997

f(0) = 0^0=1

The parity of zero is even,
So we replace x with zero:
f(0)=0^2=0
