  1. Describe what a function does in your own words

a) A function is a repeatable process. Input goes in, the process occurs, and then output comes out.

  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) = 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.

a) f (x ) = { (x / 4) – 5 }

  1. A function is a binary expression involving one or multiple variables in which an input (x) goes through a mathematical equation to produce an output result ( y = f (x) ).

  2. f (2) = 2^2 = 4

    f (7) = 7 + 10 = 17

    f (0) = 0^2 = 0

f (x) = x                  	              / : 4
f (x) = x/4	
f (x) = 0.25 * x	                      / - 5
f (x) = ( 0.25 * x ) - 5
