  1. A function is a mathematical way to represent a relation between an input and an output. It means that, basing on how the function is written, a certain input will produce a specific output. It also means that by having an output and by knowing the function from which it originates it would be possible to derive the input provided.

  2. a -> f(2)=x^2=2^2=4
    b -> f(7)=x+10=7+10=17
    c -> f(0)=x^2=0^2=0

  3. f(x)= [(x/4)-5]

  1. A function is a computation in which you assign a number to a variable. Once the number (your input) is assigned to the variable the equation can be solved and it will give you an answer (your output).

  2. A) f(x) = 2^2 = 4
    B) f(x) = 7+10 = 17
    C) f(x) = 0^2 = 0

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

  1. Describe what a function does in your own words

A function is a computation that takes 1 or more arguments, processes a calculation using those arguments and then returns the result of the calculation to the invoker of the function.

  1. 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) = x^2 = 4
  • b) f(7) = x+10 = 17
  • c) f(0) = x^2 = 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.
