Answer:

a. The point of the vertex is (h, k)

b. The equation of the line of symmetry is x=h

c. You can tell if the parabola goes up and down by checking if a is positive or negative: if it is positive then it goes up, and it goes down otherwise.

Answer:

3125 bacteria.

Step-by-step explanation:

We can write an exponential function to represent the situation.

We know that the current population is 100,000.

The population doubles each day.

The standard exponential function is given by:

$P(t)=a(r)^t$

Since our current population is 100,000, a = 100000.

Since our rate is doubling, r = 2.

So:

$P(t)=100000(2)^t$

We want to find the population five days ago.

So, we can say that t = -5. The negative represent the number of days that has passed.

Therefore:

$\displaystyle P(-5)=100000(2)^{-5} = 100000 \Big( \frac{1}{32}\Big) = 3125 \text{ bacteria}$

However, we dealing within this context, we really can't have negative days. Although it works in this case, it can cause some confusion. So, let's write a function based on the original population.

We know that the bacterial population had been doubling for 5 days. Let A represent the initial population. So, our function is:

$P(t)=A(2)^t$
