Theres no graphs but this is how the function looks like
Remember, to solve this, you multiply the bigger numbers and add the exponents. if the exponents are negative they go on the bottom and are switched to a positive, you are trying to make the problem positive.
number 15 is A because you multiply 2 and 4 to get 8 and you add the exponents together if they are positive and are not a fraction
number 16 is D because you multiply all the bigger numbers together to get 48, then you add all the b's together to get four and all the a's to get 8
number 17 is D because you do the same by multiplying 5 and 3 to get 15, then adding the exponents to get 3 x's and 6 y's
number 18 is D because you multiply 5 and 2 and add the exponents to get 3 x's and 5 y's because the x without a number is a one so you make that one count and add 2 and one together to get 3
number 19 is B because the smaller number is negative so the y goes to the bottom and it becomes a y^3
number 20 is A because both exponents are negative and go to the bottom and become positive
number 21 is D because its the same case as number 20
Lastly Number 22 is B
I hope this helps and is correct lol
Each pound of the dog food costs $1.03 .
Each pound of the cat food costs $1.02 .
If you own a dog, then the dog food is the better deal.
If you own a cat, then the cat food is the better deal.
You would not want to feed your pet on food formulated for
a different species of animal, just to save a few pennies.
For that matter, I'll bet you could save a TON of money by
feeding your whole family dog food or cat food three times
a day !
