What will be the output for the following inputs?

  • a) f(2)
    Because 2 is even
    f(2)= 2^2=4

  • b) f(7)
    Because 7 is odd
    f(7)= 7+10= 17

  • c) f(0)
    Because 0 is even
    f(o) = 0^2 = 0

  1. Describe what a function does in your own words
    A function is the application of some work or change upon an original or specific value (or number) which results in a modification or change to the original/specific value (or number) expressed as an output

    NOTE: the output may be the same (value/number) as the original/specific input or different.

  2. Calculate the output of the following function

f(x) = {

x^2 if x is even

x+10 if x is odd

}
