Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.

an exponential function titled bacteria decay with x axis labeled time, in minutes, and y axis labeled amount of bacteria, in thousands, decreasing to the right with a y intercept of 0 comma 60 and an x intercept of 18 comma 0.

0 ≤ x ≤ 18, −3.33
0 ≤ x ≤ 18, −0.3
0 ≤ y ≤ 60, −3.33
0 ≤ y ≤ 60, −0.3

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
