Write an equation to show that Y is directly proportional to x using the constant of proportionality given. Then solve for the unknown value. k = 3/11 and x = 9

y = 2

Step-by-step explanation:

y ∝ kx

y = × 9 =

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.

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 !
