Name the property used in each step
3(10-5•2)+ 21/7
=3(0)+21/7
=0+21/7
=0+3
=3

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 !
