inverse of-(2)^{-14/25 (x-21)}+25

inverse

- (2)^{- \frac{14}{25} (x - 21)} + 25

- \frac{25 ln ( 25 - x )}{14 ln ( 2 )} + 21

Solution steps

y = - 2^{- \frac{14}{25} (x - 21)} + 25

Replace

x

with

y

x = - 2^{- \frac{14}{25} (y - 21)} + 25

Solve for

y, x = - 2^{- \frac{14}{25} (y - 21)} + 25

- \frac{25 ln ( 25 - x )}{14 ln ( 2 )} + 21

f (x) = \frac{3 x - 1}{2 x + 1}

f (x) = 2 - x + 3

x - 2

f (x) = x - 5 + 2

f (x) = 5^{2 x}
