A tank filled with water begins draining. The number of minutes t since the water began draining from the tank is a function of the number of gallons of water in the tank, v. We will call this function f so that f(t) = v. Required:
a. Using function notation, represent the of gallons of water in me tank 4 minutes after the water darning from the Ink.
b. Suppose that f(4) = 7, what does this mean in the context of the problem?

(b) There are 7 gallons left in the tank after 4 minuted

Step-by-step explanation:

Given

time since water began draining

gallons in the tank

Solving (a): Notation for gallons remaining at 4 minutes

This means that

becomes

Solving (b): Interpret f(4) = 7

We have:

time since water began draining

gallons in the tank

This means that:

It can be interpreted as:

There are 7 gallons left in the tank after 4 minuted
