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.
