Question

Explain what the word function implies in the sentence: The distance Annette traveled was a function of speed and the amount of time she drove.

Answer 1

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.

`d=speed* time` or

f(speed,time) = speed x time
