Patti is using mental math to evaluate the expression( 70 + 12.8 + 30 + 6.1

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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 !
