f(1)=3f(1)=3 and f(n)=2f(n-1)+3

f(n)=2f(n−1)+3

then find the value of f(3)

f(3)=21

Step-by-step explanation:

f(1)=3

f(n)=2f(n-1)+3

n=2

f(2)=2f(2-1)+3

f(2)=2f(1)+3

f(2)=2*3+3

f(2)=6+3

f(2)=9

n=3

f(3)=2f(3-1)+3

f(3)=2f(2)+3

f(3)=2*9+3

f(3)=18+3

f(3)=21

w'x is 0.

hope it

what i would say the best answer is a. 40.5
