Question

MARKIN BRAINIEST !!!

Answer 1

for P(t) = 65- 5t

domain is [0, 13]

because intially at t = 0 total puppy available is 65 (put t = 0 in equation)

now after 13 days

P(t) = 65 - 5×13 = 65-65 = 0

no puppy available. so t has last range of 13.

similarly for second its domain is [0, ∞]

as subscribers will increase as t will increase.

for 3rd

C(t) = 65 + 5t

here t is guest so . they can only accomdate 30 guests only so t csn go to 30 only.

so domain is [0,30]
