Question

anthony owns an electric car. he accidentally left it on overnight, completely draining the battery. the charger in his garage takes 8 hours to fully charge the battery. the function p(h) represents the percentage the battery has been charged after charging for h hours. what is the domain of p(h)? all whole numbers from 0 to 8 all whole numbers all real numbers greater than or equal to 0 all real numbers from 0 to 8

Explanation:

Step1: Understand the context

The battery - charging process starts at \(h = 0\) (when charging begins) and ends at \(h = 8\) (when it's fully charged).

Step2: Define the domain concept

The domain of a function is the set of all possible input values. Here, the input is the number of hours \(h\) of charging.

Step3: Determine the range of \(h\)

The number of hours of charging can be any fraction or whole - number value between 0 and 8 (inclusive) during the charging process. So, \(h\) can be \(0\leq h\leq8\) and \(h\) is a real number.

Answer:

all real numbers from 0 to 8
