inverse of y=-2*(1/3)^x

Solution

inverse

y = - 2 \cdot (\frac{1}{3})^{x}

Solution

- \frac{ln ( - \frac{x}{2} )}{ln ( 3 )}

Solution steps

y = - 2 (\frac{1}{3})^{x}

Replace

x

with

y

x = - 2 (\frac{1}{3})^{y}

Solve for

y, x = - 2 \cdot (\frac{1}{3})^{y}

- \frac{ln ( - \frac{x}{2} )}{ln ( 3 )}
