Which of the following shows the situation below in function notation? the depth of a lake at a certain point, which is a function of the distance of that point from shore, is 30 feet. a. distance from shore(depth) = 30 ft b. distance from shore(30 ft) = depth c. depth(distance from shore) = 30 ft d. depth(30 ft) = distance from shore

C

Step-by-step explanation:

The general functional notation is:

Where it means that is a function of , and the answer is .

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.
