Question

1. What are the coordinates of P and what do they mean in this context?

2. What are the coordinates of Q and what do they mean in this context?

Answer 1

1. P(0.25 , 1.18)

2. P(1.25 , 2.37)

Explanation:

You have the following function:

`B=2^h`

1. The coordinates of P specify the amount of the population of the bacteria B, in thousands for a specific values of h.

By the subdivisions of the x-axis, you can conclude that the h value of the coordinate P is h = 0.25. Then you replace this value in the function to find B:

`B=2^(0.25)=1.18`

Then, after 0.25 hours there are 1.18 thousand of the bacteria B.

2. Once again, due to the subdivisions of the x-axis, you know that h, for point Q, is h = 1.15. You replace this value for B and you obtain:

`B=2^(1.25)=2.37`

Then, after 1.25 hours there are a population of 2.37 thousand of the bacteria B.
