inverse of f(x)=2+sqrt(4+7x)

Solution

inverse

f (x) = 2 + 4 + 7 x

Solution

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

Solution steps

y = 2 + 4 + 7 x

Replace

x

with

y

x = 2 + 4 + 7 y

Solve for

y, x = 2 + 4 + 7 y

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

Popular Examples

extreme f(x)=96x-16x^2 extreme points

f (x) = 96 x - 16 x^{2}

symmetry (x+3)^2-5 symmetry

(x + 3)^{2} - 5

extreme f(x)=(2x)/((1+x^2)^2)extreme points

f (x) = \frac{2 x}{( 1 + x ^{2} ) ^{2}}

symmetry-2(x+1)(x+1)(x-2)symmetry

- 2 (x + 1) (x + 1) (x - 2)

domain of f(x)=(x^2-9)/x domain

f (x) = \frac{x ^{2} - 9}{x}
