f(x) = {

x^2 if x is even

x+10 if x is odd

}

  1. Describe what a function does in your own words

It describes the relationship between the input and the output.

  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)

x^2 if x is even: 4
x+10 if x is odd: Not possible because x is not odd.

b) f(7)

x^2 if x is even: Not possible because x is not even.
x+10 if x is odd: 17

c) f(0)

x^2 if x is even: 0
x+10 if x is odd: Not possible because x is not odd.
