I attached a graph of the function. You could use the slope-intercept form to easily hand draw it, or of course you could graph it yourself with a graphing calculator.

The domain of a graph refers to x-values. Basically, for how many x values will you have a real value? The range of a graph refers to y-values. Just as a tip, you don't even need a graph to know that an equation in this format generally has a domain and range of all real numbers.

Anastasy [175]

Answer:

The population will be of 2400 in 36 years.

Step-by-step explanation:

The equation for the population of plants after t years follows the following format:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the initial amount of plants and r is the yearly rate which it increases.

Assuming that the initial population is 300

This means that P(0) = 300.

The doubling time of a population of plants is 12 years.

This means that P(12) = 2*300 = 600.

We use this to find r.

$P(t) = P(0)(1+r)^{t}$

$600 = 300(1+r)^{t}$

$(1+r)^{12} = 2$

$\sqrt[12]{(1+r)^{12})} = \sqrt[12]{2}$

$1 + r = 1.05946$

So

$P(t) = 300(1.05946)^{t}$

How large will the population be in 36 years

This is P(36)

$P(t) = 300(1.05946)^{36} = 2400$

The population will be of 2400 in 36 years.
