month texts
1 120
2 237
3 354
4 471

the function representing brent's texting per month is f(m) = 117m + 3. what does the 117 represent?

a. the number of texts at the start

b. the number of the month when brent was texting

c. the number of texts brent had in total

d. the number of the additional texts per month

2500

step-by-step explanation:

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.
