Complete the recursive formula of f(n)

Mathematics
1 answer:
Nitella [24]4 years ago
3 0

Answer:

F(1) = 45

<u>f(n) = f(n-1) * (4/5)</u>

Step-by-step explanation:

f(n) = 45 x (4/5)ⁿ⁻¹

f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45

f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²

<u>f(n) = f(n-1) * (4/5)¹</u> = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹

Brainliest + Points<br><br> Can you please explain why choice A. is correct?
tankabanditka [31]

Answer: because that is what the slope would look like

Step-by-step explanation:

when you graph this, you have a point at 2, 4 and 0, 8. when you go to 0, 8 and count down four so you now have to move to the right to get to 2, 4. You then move to the right 2 spaces. so, you moved (-4, 2) since this can be simplified, you then have (-2, 1) which is equal to -2. If this still doesnt make sense, go to Desmos.com and put (2,4) click the plus button then add expression then type (0,8). Count down -4 and over 2. Hope this helps
