Step-by-step explanation:
Answer:
f(n+1) = 13
Step-by-step explanation:
- We know that f(1) = 15
- So we can substitute this for f(n)-3
- With this:
- f(n+1) = f(1) -3
- f(n+1) = 15-2
- f(n+1) = 13
F(-3) = -2(-3)2 - 5(-3) +4
- 6 x 2 -15 + 4
- 12 -15 +4
- 27 + 4
-23
I believe this is how to solve the equation. I could be wrong.
