F(n) = 2• (-3)^n
Mashutka [201]

Answer:

f(1)=-6

f(n)=f(n-1)(-3)

Step-by-step explanation:

We are given that

f(n)=2\cdot (-3)^n

We have to complete  the recursive formula of f(n).

Substitute n=1

f(1)=2\cdot (-3)

f(1)=-6

f(2)=2\cdot (-3)^2=18

f(3)=2\cdot (-3)^3=-54

\frac{f(2)}{f(1)}=\frac{18}{-6}=-3

\frac{f(3)}{f(2)}=\frac{-54}{18}=-3

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

f(n)=f(n-1)r

f(n)=f(n-1)(-3)

PLEASE HELP RN
yulyashka [42]

Step-by-step explanation:

y = -9x - 45 -5

y = -9x - 50

slope = x coefficient = -9

we can use the point where

x = 0

y = -50

P1 (0, -50)

and when y = 0

-9x = 50

x = -50/9

P2 = (-50/9 , 0)
