  1. Describe what a function does in your own words - A function is an equation that takes inputs and produces outputs.
  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) = Null
  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.

1. Describe what a function does in your own words function is a computation that takes an input and process the output for us.

2. Calculate the output of the following function

  • a) 4 - f(2) = 2^2
  • b) 17 - f(7) = 7+10
  • c) 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

  2. Calculate the output of the following function

Answer: 1. A function is a rule that defines a relationship where there is an input (range) and output (domain)

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) output 4
  • b) f(7) output 17
  • c) f(0) output 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.
