    A function is a computational process that converts an input into 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)
    f(x) = x^2 if x is even, x+10 if x is odd
    f(2) = 2^2
    f(2) = 4

  • b) f(7)
    f(x) = x^2 if x is even, x+10 if x is odd
    f(x) = 7+10
    f(x) = 17

  • c) f(0)
    f(x) = x^2 if x is even, x+10 if x is odd
    f(x) = 0^2
    f(x) = 0
