inverse of f(x)=4x+9

Solution

inverse

f (x) = 4 x + 9

Solution

\frac{x - 9}{4}

Solution steps

y = 4 x + 9

Replace

x

with

y

x = 4 y + 9

Solve for

y, x = 4 y + 9

\frac{x - 9}{4}

Popular Examples

domain of (sqrt(4-x))/((x+1)(x^2+1))domain

\frac{4 - x}{( x + 1 ) ( x ^{2} + 1 )}

range of f(x)=(x+20)^2-30 range

f (x) = (x + 20)^{2} - 30

inverse of f(x)=\sqrt[3]{6x-5}inverse

intercepts of y=2x-4 intercepts

y = 2 x - 4

shift f(x)=cos(1/2 x)shift

f (x) = cos (\frac{1}{2} x)
