The value, v(m), of a comic book m months after publication has an average rate of change of –0.04 between m = 36 and m = 60. which statement must be true?
the value of the comic book decreased by a total of $0.04 between m = 36 and m = 60.
the value of the comic book increased by a total of $0.04 between m = 36 and m = 60.
the value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.
the value of the comic book increased by an average of $0.04 each month between m = 36 and m = 60.

C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

The average rate of change for the function f(x) from and is

It is a measure of how much the function changed per unit, on average, over that interval.

Actually, this is the slope of the line passing through two points on the graph of the function.

If the average rate of change of the function f(x) between m = 36 and m = 60 is -0,04, it means that the value of the comic book decreased (because of negative number -0.04) by an average of $0.04 each month (a unit in this case is a month) between m = 36 and m = 60.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
