inverse of f(x)=sqrt(5x+4)

Solution

inverse

f (x) = 5 x + 4

Solution

\frac{x ^{2} - 4}{5}

Solution steps

y = 5 x + 4

Replace

x

with

y

x = 5 y + 4

Solve for

y, x = 5 y + 4

\frac{x ^{2} - 4}{5}

Popular Examples

domain of f(x)=2x+6 domain

f (x) = 2 x + 6

domain of f(x)=(6x+5)/(5x-2)domain

f (x) = \frac{6 x + 5}{5 x - 2}

midpoint (-1,-4),(4,-1)midpoint

(- 1, - 4), (4, - 1)

intercepts of y=-x^2-8x-12 intercepts

y = - x^{2} - 8 x - 12

distance (-2,4),(-2,-4)distance

(- 2, 4), (- 2, - 4)
