Option a: The number of bacteria at time x is 0.

Option b: An exponential function that represents the population is y=200(1.5)^x

Option c: The population after 10 minutes is 11534(app)

Explanation:

It is given that the coordinates of the graph are (0,200), (1,300) and (2, 450)

Option a: To determine the number of bacteria x when y = 200

From the graph, we can see that the line meets y = 200 when x = 0

Thus, the coordinates are (0,200)

Hence, the number of bacteria at time x is 0 when y = 200.

Option b: Now, we shall determine the exponential function of the population.

The general formula for exponential function is y=a \cdot b^{x}

Where a is the starting point and a=200

b is the common difference.

To determine the common difference, let us divide,

\frac{300}{200} =1.5

Also, \frac{450}{300} =1.5

Hence, the common difference is b=1.5

Thus, substituting the values a=200 and b=1.5 in the formula y=a \cdot b^{x},

we have, y=200(1.5)^x

Hence, An exponential function that represents the population is y=200(1.5)^x

Option c: To determine the population after 10 minutes, let us substitute x=10 in y=200(1.5)^x, since the x represents the population of the bacteria in minutes.

Thus, we have,

\begin{aligned}y &=200(1.5)^{x} \\&=200(1.5)^{10} \\&=200(57.67) \\&=11534\end{aligned}

Hence, the population after 10 minutes is 11534(app)

So just add all of them together and you get 405. Then divide by the amount of numbers there is which is 5. So 405 divided by 5. The answer is 81.
