A function is a defined set of procedures about how to process provided input in order to generate output. For example, a function can be a defined computation that takes in numerical variables as input, processes the input in a defined way to generate output.

f(x) = {

x^2 if x is even

x+10 if x is odd

}

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

[ahmed.jamali]

My biggest nightmare is Maths, I skipped Engineering to avoid maths. I understood the video, but couldn’t understand the question at all. It brought back the horrifying memories of me failing in maths tests. I will learn the math and come back again. I’m sure , I will be able to do it now because I see a more practical sense of it.

[Tim_85]

A function is a math formula where you can alter an input with a variable to get an output.

[Tackler]

1. Describe what a function does in your own words
   A function is a mathematical formula designed for a specific purpose. Within any function, there can be as few as one variable or can have many variables depending on the purpose of the function. With any function there is always an input and an output result.
