Given f (9)= -2, which function can be used to generate
the sequence -8 , -7.25, -6.5, -5.75 ?
1. f(n) = 8+0.75n
2. f(n) = -8 -0.75 (n-1)
3. f(n) = -8.75 + 0.75n
4. f(n) = 0.75 + 8(n-1)

f(n)= -8.75 + 0.75n

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.
