2. the humane society has puppies for adoption. the weights, in pounds, of the puppies currently at the humane society are 17, 14, 13, 15, 21, 39, 18, 22, and 14. (a) create a stem-and-leaf plot of the weights of the puppies. (b) what is the weight difference between the heaviest puppy and the lightest puppy? (c) how many puppies are currently at the humane society? what weight interval has the most puppies? what fraction of the total does this interval represent?

Do you need with the x value for the minimum? its always between the two intercepts for a parabola

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
