A. what is the domain?
b. what does the domain mean in terms of the problem?

a. what is the range?
b. what does the range mean in terms of the problem?

a. when is the function decreasing?
b. what does this decreasing interval mean in terms of the problem?

Step-by-step explanation:

Q.No.5

A) Domain is all the values that x can take.  In the graph we see that domain is

the values of x from 0 to 12 hours

Domain is 0≤x≤12

B) Domain is the no of hours as per the graph i.e. lower limit 0 to 12 hours

A) Range is the values what y can take.  Here the values temperature can take

From the graph we find that range is -2 to 4

-2≤y≤4

B) Range is the values what y can take.  Here the values temperature can take

A) Decreases whenever y decreases as x increases. Here. decreases for

x=0 to x=2

B) Decreasing interval is (0,2) and this means whenever number of hours increases the temperature decreases.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
