Help don’t understand it

D.

Step-by-step explanation:

The domain is the interval of x numbers. In this case the x values go from 0 to 10.

We know 10 is the maximum because they have said so as there are only 10 tickets available at a time. Also the graph agrees with that.

So the answers cannot be A or C since there is a limit to the domain.

B cannot be the answer since there cannot be fractional tickets (1 1/2, 5 1/8 etc.). The tickets are countable and they should be whole numbers. Real numbers include fractions, decimals too.

Therefore, the answer is D.

Hope this helps! :)

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
