Question 14 of 20
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.

In function notation, we can express the depth of the lake at a certain distance from the shore as . This means that regardless of how far you are from the shore (the distance ), the depth remains consistently 30 feet.

Function notation serves as a neat shorthand for illustrating relationships between variables. In this case, it signifies that there’s no change in depth as you move away from the shore, making it easy to recognize the lake’s characteristics in mathematical terms. So, next time you’re at the lake, feel free to impress your friends with that fun fact!
