One of your company's salesmen estimates he will drive 20,000 miles this year and each of the next two years. As the service manager for the company's fleet of six-cylinder compact automobiles, you are asked to determine the total costs for each of the three years. Year 1 Total Cost: $ Year 2 Total Cost: $ Year 3 Total Cost: $

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

0.02040816326

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 !
