inverse of f(x)=sqrt(7x+4)

Solution

inverse

f (x) = 7 x + 4

Solution

\frac{x ^{2} - 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 ^{2} - 4}{7}

Popular Examples

inflection f(x)=3x^4-4x^3-5x^2 inflection points

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

parity f(x)= x/(x^2-7)parity

f (x) = \frac{x}{x ^{2} - 7}

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

\frac{x}{x ^{2} - 4}

inverse of f(x)= 1/4 x-5 inverse

f (x) = \frac{1}{4} x - 5

inverse of f(x)=log_{4}(x)+10 inverse

f (x) = lo g_{4} (x) + 10
