inverse of f(x)=7x-4

Solution

inverse

f (x) = 7 x - 4

Solution

\frac{x + 4}{7}

Solution steps

y = 7 x - 4

Replace

x

with

y

x = 7 y - 4

Solve for

y, x = 7 y - 4

\frac{x + 4}{7}

Popular Examples

range of y=log_{3}(x)range

y = lo g_{3} (x)

f (x) = 2 x - 1

domain of f(x)=sqrt((x^2-5x+4)/(3-x))domain

f (x) = \frac{x ^{2} - 5 x + 4}{3 - x}

inverse of f(x)=-x^2+11 inverse

f (x) = - x^{2} + 11

critical sqrt(25-x^2)critical points

25 - x^{2}
