  1. Describe what a function does in your own words
    A function gets an input, calculates sth. predefined and delivers the output in the end

  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) 4

b) f(7) 17

c) f(0) 0

  1. I like to think of functions as machines. You put something in, something magical happens, and then you take something new out. Just like a printer’s function is to print things, a mathematical function basically performs some computation and gives the result.

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

  1. Describe what a function does in your own words
    A function is a computation.When you give a function an input you will get an output.

  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)=2^2=4
* b) f(7)=7+10=17
* c) f(0)=0^2=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

example
f(12)=(12/4)-5=-2
