  1. Describe what a function does in your own words

A function transform (or not) an input value with fixed rules written into. Rules never changes 'til the code of function is not modified. It return always something.

  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 mathematical expression that explains the relationship between your input and the kind of output you expect/observe. The input is represented by the variable x and the output by y or f(x).

  2. If f(x) = x^2 if x is even
    f(x) = x+10 if x is odd
    Then
    a. f(2) = 4
    b. f(7) = 17
    c. f(0) = 0

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

  1. A function is a set of rules that will give you an output based on what the equation is given.

A. f(2) = 4 this function dictates that we will be taking (x) which is 2 in this case and it is multiplied by is self because it is even.
B. f(7) = 17 We are given an odd number so the function will add 10
C. f(0) = 0 In the case of zero we do not have an odd or even number, so the output is 0.
3. f(x)=(x/4)-5
