So in the thing p=m/v to find m would you times v by p?

M = mass

p = density

v = volume

Yes, to find m it would be m = pv.

To find v that would be m/p.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
