inverse of f(x)=log_{2/5}(x)

Solution

inverse

f (x) = lo g_{\frac{2}{5}} (x)

Solution

(\frac{2}{5})^{x}

Solution steps

y = lo g_{\frac{2}{5}} (x)

Replace

x

with

y

x = lo g_{\frac{2}{5}} (y)

Solve for

y, x = lo g_{\frac{2}{5}} (y)

(\frac{2}{5})^{x}

Popular Examples

parallel y=7x-3 parallel

y = 7 x - 3

intercepts of f(x)=(2x^2+3)(x^2-5)intercepts

f (x) = (2 x^{2} + 3) (x^{2} - 5)

intercepts of f(x)=2x^2+8x+12 intercepts

f (x) = 2 x^{2} + 8 x + 12

asymptotes of f(x)=sqrt(9x^2-6x)-3x asymptotes

f (x) = 9 x^{2} - 6 x - 3 x

domain of f(x)= 2/((x+5)^2)domain

f (x) = \frac{2}{( x + 5 ) ^{2}}
