inverse of f(x)=x^2+4

Solution

inverse

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

Solution

x - 4, - x - 4

Solution steps

y = x^{2} + 4

Replace

x

with

y

x = y^{2} + 4

Solve for

y, x = y^{2} + 4

x - 4, - x - 4

Popular Examples

critical f(x)=20x^3-5x^4 critical points

f (x) = 20 x^{3} - 5 x^{4}

asymptotes of x/(x^2-16)asymptotes

\frac{x}{x ^{2} - 16}

line (0,4),(2,0)line

(0, 4), (2, 0)

asymptotes of f(x)=(3+2x)/x asymptotes

f (x) = \frac{3 + 2 x}{x}

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

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