You are correct in stating you have a decay. This is because the base of the exponential 0.82 is in the form 1+r where 1+r = 0.82 solves to r = -0.18

The negative r value means we have decay.

The rate of decay is 18% since 0.18 = 18/100 = 18%

For example, if we started with 100 items then after 1 unit in time, you'd have 82 items since 100-18 = 82

Which graph represents a reflection of f(x) = (10)x across the y-axis?
Aleks [24]
We are asked in the problem to determine the graph that represents the reflection of f(x) = 10^x. This function is an exponential function that is also asymptotic to the y axis. Asymptotic means that a function approaches a number at the x or y axis but not necessarily touching it. In this case, the function is asymptotic to y =0. The graph of f(x) = 10^x is attached on this answer. The reflection is simply taking f(-x) as we substitute -x to x. The resuting function is f(x)= 10 ^ -x. We can see from the graphs that they mirror each other at x = 0.
