  1. Describe what a function does in your own words
    A function is a mathematical operator that receives an input and delivers an output, performing some operation that does the indicated conversion.
  2. Calculate the output of the following function
f(x) = {

x^2 if x is even

x+10 if x is odd

}

  1. Describe what a function does in your own words

Functions are a formula that takes an input and applies computations to obtain an output.

  1. Calculate the output of the following function
  • a) x = 4
  • b) x = 17
  • c) x = 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

f(32) = (32/4)-5 = 16-5 = 11

  1. describe what a function does in your own words.
    A function is a computation, a function is the varible of that computation.

  2. calculate the output of f(x) = x^2 if x is even, example x=2 f(2)=4 so f would be 2.
    if odd f(x)= x+10. f(7) = 7+10
    f(0) =10

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