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 high of Pooja's plant (in centimeters), t days after she bought it.

Which number type is more appropriate for the domain of h?

A. Integers

B. Real numbers

What's the appropriate domain?

A. 2≤ t ≤30

B. 0≤ t ≤100

C.-2≤ t ≤98

D. 0≤ t ≤30

B. Real numbers

C. - 2≤ t ≤98

Step-by-step explanation:

t is the no. of days.

There can be 2.5 days too,

So domain should be Real numbers

t days after she bought it,

So 2 days before t = - 2

So, - 2≤ t ≤98

Solution:

Total number of Days that Pooja's plant survived = 2 + 98 = 100 Days = (t)

Longest Height obtained by plant = 30 cm = h

As the two, i. e number of Days lived by plant and it's longest height obtained are directly proportional.

We will solve it by unitary method.

100 Days = 30 cm

1 cm = Days

If height of the plant is h cm, and amount of time taken is t days, then

h (t) cm =, for t=0,1,2,3,4,5,6 ... we get different values of h.
