Answer:
A function tells a relationship between an input(there can be more than one) and a single output.
Given statement is - the distance Annette traveled was a function of speed and the amount of time she drove.
Here, the word function tells us, that for a given input (speed and time in this case) there is a single output (distance) that Annette drove.
Moreover, we know that distance is the product of speed and time.
[tex]d=speed\times time[/tex] or
f(speed,time) = speed x time
