If a sequence is defined recursively by f(0) = 2 andf(n +1) = -2f(n) + 3 for n ≥ 0, then f(2) is equal to

Answers

Answer 1

Answer: If you would like to know how much is f(2), you can calculate this using the following steps:

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.

Answers

Answer:

A) y=2x-1

Step-by-step explanation:

y-y1 = $(y2-y1)/(x2-x1)$ (x-x1) => y-3 = $(7-3)/(4-2)$ (x-2) => y-3= 2x-4 => y=2x-1
