  1. Describe what a function does in your own words

A function is a computation that when we insert an input a certain output is given.

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

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

  1. A function is a computation where a syntax (f) receives an input (x) and then computes a new output that depends on the input.

  2. If input is even [x(2)]: f(2) = 4
    If input is odd x+10: f(7) = 17
    If input is even [x(2)]: f(0) = 0

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