inverse of f(x)=f(x)= 1/2 (4)^x

inverse

f (x) = f (x) = \frac{1}{2} (4)^{x}

\frac{ln ( 2 x )}{2 ln ( 2 )}

Solution steps

y = \frac{1}{2} \cdot 4^{x}

Replace

x

with

y

x = \frac{1}{2} \cdot 4^{y}

Solve for

y, x = \frac{1}{2} 4^{y}

\frac{ln ( 2 x )}{2 ln ( 2 )}

y = lo g_{10} (- x - 1)

4 - 8 - 8 x, x \leq 1

2 - 3 x^{2}

f (x) = 3 x^{2} + 3

\frac{13}{x ^{2}}
