Mina Rios · Answer 1

A, D and E are all true.

I believe option F is incomplete. If the initial value is stated as being 49, then F is also correct.

Donovan Oconnell · Answer 2

The quick answer is;

- The domain is the set of all real numbers.

- The range is y > 0. - As x increases by 1, each y-value is one-seventh of the previous y-value.
