A function provides an outcome/output depending on the input.
@SpyrosGR Of course. Multiplication and division are always done before addition and subtraction.

1- A function associates two sets of elements, in our aproach, those elements can be numbers. And it associates them in a way that for every element in the first set there is one and only one element of the second set associated. So if we have sets A and B as our two variables, where x belongs to A and y belongs to B then y = f(x). In other words, an output y is determined by an equation over an intput x.
2- f (2) = 4
f (7) = 17
f (0) = 0
3- f(x) = (x/4) - 5

Describe what a function does in your own words
Instructions set up for an input to activate and result in an output -
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 - 5

First I’d like to say that question 1 and 3 are easy enough to understand and come up with an answer. However, question 2 wasn’t clearly written in the display of the functions we are supposed to use. Input (abc) are clear enough. But it leaves me to work backwards and use the feedback of others and decide who is right or wrong.
1- is code that uses a preset equation to take an input and to give an output.
2- Outputs
f(2) = 2^2 is 4
f(7) = 7+10 is 17
f(0) = 0x0 is 0
3 f(x) = (x/4)-5

I’m glad you asked, because I was thinking the same thing.
What I realized was that the math was easy enough, but question 2 was not clearly written in order to understand what the function (equations) were.
Looking in your replies I found the answer… Thanks to that guy!

Jesus this question was so confusing to me. Was stuck on this for ages not knowing where the variable of 7 was coming from at all trying to figure out the first part of the question first. But anyway…

A function performs a mathematical task applied to a variable input
A) Where x = 2 (even number) x² = 4
B) Where x = 7 (even number) x + 10 = 17
C) Where x = 0 (even number) x² = 0
- f (x) = (x/4) - 5

I suck at math, so let me know if I’m missing something here 
1. Describe what a function does in your own words
A function is kind of like a rule. From a mathematical standpoint this is basically a command to take an input and do something with that input.
Ex. When you have X, do Y (add 1, or multiply by 2, for example).
2. 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

- A function is a computation that is given an input and returns an output.
(Assuming “^” means “to the power of”)
2a.
f(x) = f(x^2)
f(2) = 2(2^2)
= 8
2b.
f + x = f + 7
f + 7 = 10 + 7
=17
2c.
f(x) = 2(x^2)
f(0) = 2(0^2)
= 0
- f(x/4) = 10(x/4) - 5
2A. When you input x in f(x)=x^2 you get 2^2 which is 4. It seems you added an additional 2 by accident.
It should be f(x) = {x/4}-5. How did you get to the number 10? Also when writing a function that takes an x you always start with an f(x)=“your equation”
