Homework on Functions - Questions

Describe what a function does in your own words

A function is a computation where we have an input and an output. The input is a formula where we can give x different values and we get different outputs.

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

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
