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) will return 4
  • b) f(7) will return 17
  • c) f(0) will return 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.

A function takes an input, throws it through a set of rules, and returns an output.

f(2) = 2^2 = 4
f(7) = 7+10 = 17
f(0) = 0

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

  1. Describe what a function does in your own words.
    Functions are computations that have an INPUT; the function performs a calculation based upon that input, then results in receiving another number as 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): 2Squared=4
    b) f(7): 7+10=17
    c) f(0): 0Squared=0 (assumes 0 is an even integer)

  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
    …so
    f(20)=(20/4)-5=5-5=0
    f(28)=(28/4)-5=7-5=2

  1. The word that’s been used to describe a function was computation, in other words to calculate. Even more simplified. To let the computer do the work based on mathematical rules. We just have to determine which function, F, H or whatever, the input, (x) and check the output, = … ,if required.

  2. a) f(2) = 4
    b) f(7) = 17
    c) f(0) = 0

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