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

Solution for f(n+1)=3f(n) equation:

Simplifying
f(n + 1) = 3f(n)

Reorder the terms:
f(1 + n) = 3f(n)
(1 * f + n * f) = 3f(n)
(1f + fn) = 3f(n)

Multiply f * n
1f + fn = 3fn

Solving
1f + fn = 3fn

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-3fn' to each side of the equation.
1f + fn + -3fn = 3fn + -3fn

Combine like terms: fn + -3fn = -2fn
1f + -2fn = 3fn + -3fn

Combine like terms: 3fn + -3fn = 0
1f + -2fn = 0

Factor out the Greatest Common Factor (GCF), 'f'.
f(1 + -2n) = 0

Subproblem 1
Set the factor 'f' equal to zero and attempt to solve:

Simplifying
f = 0

Solving
f = 0

Move all terms containing f to the left, all other terms to the right.

Simplifying
f = 0
Subproblem 2
Set the factor '(1 + -2n)' equal to zero and attempt to solve:

Simplifying
1 + -2n = 0

Solving
1 + -2n = 0

Move all terms containing f to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -2n = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2n = 0 + -1
-2n = 0 + -1

Combine like terms: 0 + -1 = -1
-2n = -1

Add '2n' to each side of the equation.
-2n + 2n = -1 + 2n

Combine like terms: -2n + 2n = 0
0 = -1 + 2n

Simplifying
0 = -1 + 2n
