This is not a specific question, but if an equation was given and you were told that f(4)= 2f(2), how would you find f(8)?

It is not possible to know what f(8) is from this this information alone. Functions come in many forms.

You wouldn't without more information.

"If an equation was given..."
Is this equation the formula for the function f?
