Question

Pooja's plant began sprouting
\[2\] days before Pooja bought it, and she had it for
\[98\] days until it died. At its tallest, the plant was
\[30\] centimeters tall.
\[h(t)\] models the height of Pooja's plant (in centimeters),
\[t\] days after she bought it.
What's the appropriate domain?

Answer 1

Since t is "days after she bought it," t = 0 is the purchase. The plant began sprouting 2 days before purchase, so the earliest relevant time is t = -2. She had it for 98 days until it died, so the latest relevant time is t = 98.

Domain: -2 ≤ t ≤ 98 (days).
