  1. Describe what a function does in your own words

A function means when you put into an input, it will calculate an output.

  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.
    f(x) = x/4-5

  1. A Function is a computation that provided an input performs some operation on it resulting in an output. in a deterministic way (you always get the same output).
  1. a) f(2) = 4
    b) f(7) = 17
    c) f(0) = 0
  1. f (x) = (x/4) - 5

f(x)=0 when x is 0

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

  1. 4
  2. 17
  3. 0

  1. Describe what a function does in your own words
    A computation in which you define the input. The function then generates an output.

  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)=0, unresolved
  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…as described verbatim would be:
    Let f(x)=x/4
    f(f(x))=f(x)-5

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