inverse of f(x)=sqrt(5x+15)

Solution

inverse

f (x) = 5 x + 15

Solution

\frac{x ^{2} - 15}{5}

Solution steps

y = 5 x + 15

Replace

x

with

y

x = 5 y + 15

Solve for

y, x = 5 y + 15

\frac{x ^{2} - 15}{5}

Popular Examples

domain of f(x)=sqrt(t-16)domain

f (x) = t - 16

symmetry 5x^2-4y^2=2 symmetry

5 x^{2} - 4 y^{2} = 2

midpoint (-3,-4),(-5,-3)midpoint

(- 3, - 4), (- 5, - 3)

critical f(x)=-x^2+4x-4 critical points

f (x) = - x^{2} + 4 x - 4

extreme f(x)=-x^4+8x^2+6 extreme points

f (x) = - x^{4} + 8 x^{2} + 6
