a function is a written command to a computer based on a pre-determined set of rules and conditions.
- a=4
b=17
c=0 - f(x) = {x/4}-5

it calculates an Output depending on the Input and the source Code we programmed

Hi Ken, this is very well explained. I struggled with this as math is a bit of a nightmare. But this explanation has given me hope. Thank you for sharing

You are most welcome. The question might have been written a touch clearer, but honesty I am amazed Ivan has done such a great job considering English is not his native language. Always remember persistence overcomes resistance!

- Describe what a function does in your own words
Function is actually a computation of mathematical calculations and algorithms. The function is the algorithm which we want to be solved after the inputs we give and it gives back the output after the mathematical calculation of the algorithm.
- Calculate the output of the following function
f(x) = { x^2 } if (x) is even or
f(x) = { x+10} if (x) is odd
What will be the output for the following inputs?
a) f(2) because number 2 is an even number we take the case f(x) = { x^2 }
so f(2) = { 2^2 } = 4
b) f(7) because number 7 is an odd number we take the case f(x) = { x+10 }
so f(7) = { 7+10 } = 17
c) f(0) because number 0 is an even number we take the case f(x) = { x^2 }
so f(0) = { 0^2 } = 0
For those who donāt know ^ this symbol in mathematics always means to the power of, that means if you take (a) as an example f(2) = 2^2 or simplier f(2) = 2x2.
If we had to the power of 4 (^4) and took the f(2) as a factor then we would have f(2) = 2^4 which would mean f(2) = 2 x2 x2 x2 = 16
And for those who play cambling games 0 is zero and is not even or odd. This is only in gambling games like roulete! In math 0 is always even and actualy the first even number thats why 10-20-30 so on are even numbers like 12-24-36 and so on ā¦ 
- 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 } the mathematical actions in ( ) are always done first

A function performs an action on an input variable and calculates an output.
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

A function is basically a computation that has inputs and outputs. The difference between the input and output will be a given in an equation.
Ā· a) f (2) = 4
Ā· b) f (7) = 17
Ā· c) f(0) = 0
- f (x) = (x/4) - 5

1. Describe what a function does in your own words
A function is a computation that changes a data input into a the desired data output. The value of a function is to automatically calculate the correct output from the data input, thereby reducing time cost and errors from manual computations, especially at high volume.
2. Calculate the output of the following function
f(x) = {
**x^2 if x is even**
(f(4) = {8)
**x+10 if x is odd**
(f(5) = {15)
}
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) = /4-5

I try my best Helping others or cooperating with others to get a good resolt,is my pleasure and is for me like being creative. Creativity is one of the things that schools donāt teach anymore and people have forgoten how through creativity you can build up a better you and a better world. Creativity is proven to open the imagination and imagination is a very powerful aspect in live, with both imagination and creativity you can build things no one has imagined, think deep- think big

we appreciate it a lot! Thanks for helping others.
by the way, explaining things to others make you learn it yourself even better.
ps. Iām also a creative (chaotic) mind

Agree. Even if you are an expert in one thing(for example mathematics) you will always learn other things from others. Learning is a procces in our hole life, btw student4life too
