A function relates an input to an output. … It is like a machine that has an input and an output. And the output is related somehow to the input. Some function are reversible and some are not, like hash function that are used in blockchain technology. The aim of this exercises is to have idea about function in general.
a) f(2), 2 is the input for the function and 2 is even number, even number means a number which is divisible by 2 and generates a remainder of 0.
f(2) = x^2= 2^2= 4, 4 is the output.
b) f(7), 7 is odd number
f(7) = x+10 = 7+10 = 17
c) f(0), 0 is an even number
f(0) = 0^2 = 0

  1. Describe what a function does in your own words
    Functions perform predefined actions or calculations based on the given input and will output the result.
  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)
b) f(7)
c) f(0)
a) 4
b) 17
c) 0
