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

Ifigured out the question and i dont know what to put here

The last time i bought this product , it cost $20.00 but it looks like it cost 29. 60 today? what is the increase

The multiplication property of zero states that the product of any number and 0 is 0. what must be true about either a or b to make ab=0
