Question

Which of the following could be an example of a function with a domain [a,���������) and a range (-���������,b] where a>0 and b>0

Answer 1

I got B

Answer 2

I'm thinking that is the correct option.

Let a = 4 and b = 5. 4>0 and b>0

y = -1* sqr(x-4) + 5 ---> Take a look at the graph here;

Answer 3

Click on real value plot.

While y does become negative, the Domain and Range adhere to the problem requirements.

It is dicey to make a general conclusion based on one example. But I think option B is correct as you posted.
