If f(1) = 1 and f(n) = f(n-1)2 – 4 then find the value of f(4).

Pie

F(1) = 2

f(2) = -5f(2-1) = -5f(1) = -5(2) = -10

f(3) = -5f(3-1) = -5f(2) = -5(-10) = 50

So, f(4) = ?

vlabodo [156]

$\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}\\\\
-------------------------------\\\\
\cfrac{2^5}{8}\qquad \boxed{8=2^3}\qquad \cfrac{2^5}{2^3}\implies 2^5\cdot 2^{-3}\implies 2^{5-3}\implies 2^2$
