Solution for f(x)=ln(abs(x^2-16)) equation: 


Simplifying
f(x) = ln(abs(x2 + -16))

Multiply f * x
fx = ln(abs(x2 + -16))

Reorder the terms:
fx = ln(abs(-16 + x2))
fx = ln((-16 * abs + x2 * abs))
fx = ln((-16abs + absx2))
fx = (-16abs * ln + absx2 * ln)
fx = (-16ablns + ablnsx2)

Solving
fx = -16ablns + ablnsx2

Solving for variable 'f'.

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

Divide each side by 'x'.
f = -16ablnsx-1 + ablnsx

Simplifying
f = -16ablnsx-1 + ablnsx
