Jennie has a jar containing 800 mL of wax that she uses to make candles for her school project. She uses 50 mL of wax from the jar to make one candle.

The function A(n)=800−50n represents the amount of wax left in the jar after making n candles.

What is the domain of the function A(n) in this context?

Answer:

D € [0, 16]

Step-by-step explanation:

if you were looking at this from a purely mathematical sense the domain would be infinite but here the number n can't be negative because it is impossible to make negative candles and the function A(n) can't be negative because you can't have negative wax.

it would help to draw the function and look for the values of n in the first quadrant (where both n and A(n) are positive) and that is the domain.

the most candles you can make is 800-50n = 0

n = 800/50 = 16

the domain is

D € [0, 16]
