Question

Which of the following shows the situation below in function notation?

Answer 1

Answer:

C

Step-by-step explanation:

The general functional notation is:

$f(x)=A$

Where it means that $f$ is a function of $x$, and the answer is $A$.

From the problem, we know that the depth is a function of distance, and at that specific distance, the depth is 30 ft.

So we see that depth is a function of distance from shore, and the answer is 30 ft.

Matching this to our explanation of functional notation above, we can say that:

Depth(distance from shore) = 30 ft

Answer C is right.
