  1. Describe what a function does in your own words
    Function relates an input to output, A function does create a formular to perform different mathematical operations.

What will be the output for the following inputs?

  • a) f(2) = 4
  • b) f(7) = 17
  • c) f(0) = 0
  1. 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
}
f(x) = (x/4) - 5

A function takes the instruction(s) written and performs it when needed without failure or abuse. So if a parameter is set, the function will act once the parameter is met.

  1. A function is something i tell a computer pgrogramm to do. I programm the function first to act a certain way i like i give an input and want the output by the rules of the function i coded.

I discribe first what the imput is with a variable and at the output funktion with the attribute i want to have in the output

2:
a) f(2) = 2 x !2 = 4 first function because 2 is even
b) f(7) = 7 + 10= 17 second function because 7 is odd
c) f(0) = 0 x !2 = 0 first function because 0 is even

f(x) = {

x = / 4 (-5)

}

Dont know if the code is right like that…

  1. Describe what a function does in your own words

A function is a program of instructions to return a computed value on the input or argument that was passed to it when it was invoked.

  1. Calculate the output of the following function
    Function to return a value based on whether the input is odd or even
    If the input is even multiply it by itself
    If the input is odd add 10 to it

Therefore:
a) 2 returns 4
b)7 returns 17
c) 0 returns 0

Function is same as computation. Computation is made of three elements : input ,output and some calculation between this two.

So 1) F(x)=22=4
2) F(x)=7+10=17
3) F(x)=02=0

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