[BShehaj]

Q: Describe what a function does in your own words

A: It is a computation. When you give an input you get an output based on the function structure.

Q: 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)

A: 2 is even, so:

f(2^2) = 4

b) f(7)

A: 7 is odd, so:

f(7+10) = 17

c) f(0)

A: 0 is even, so:

f(0^2) = 0

Q: Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.

A: f(x) = x/4 - 5
