Answer:

<h2>A,and C!!</h2><h3>Always use the line test. draw lines through the lines in the graph and see if any line, lines up. (It should never line up if it's a function.</h3><h3 /><h3>E is a function because none of the dots are lined up.</h3><h3 />

D is not a function because it has 2 dots that makes a line (2 dots are lined up) and B is intersecting

With no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.

<h3>What is an exponential function?</h3>

Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.

A type of plant is introduced into an ecosystem and quickly begins to take over.

A scientist counts the number of plants after m months and develops the equation to model the situation, which is given as,

$p(m)=19.3(1089)^m$

Most recently, the scientist counted 138 plants.

$138=19.3(1089)^m\\(1089)^m=7.15$

Taking log both sides of the equation,

$\log(1.089)^m=\log7.15\\m\log(1.089)=\log(7.15)\\m=\dfrac{\log7.15}{\log(1.089)}\\m\approx23.1$

Thus, with no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.
