Question 5 The half-life of iodine-131 is 8 days. The amount of a 100 gram
sample of the isotope left d days after being introduced is
I = 100 (½)^d/8
What is the percent change per day?

A. 8.3% decrease per day
B. 91.7% decrease per day
C. 50% decrease per day
D. 99.6% decrease per day

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
