Q. Thanks to an online typing course, Audrey has become a much faster typist. The function

f(x)

gives how many words she can type in

x

seconds.

\newline

What does

f(45) = 68

tell you?

\newline

Choices:

\newline

(A)

\text{Audrey can type \( 68 \) words in \( 45 \) seconds.}

\newline

(B)

\text{Audrey can type \( 45 \) words in \( 68 \) seconds.}

Define $f(x)$ : $f(x)$ tells us the number of words Audrey can type in $x$ seconds. So, $f(45)$ means the number of words she can type in $45$ seconds.
Interpret $f(45)$ : $f(45) = 68$ means that Audrey can type $68$ words in $45$ seconds, not the other way around.
