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

domain of sqrt((x^2+5x+6)/(x+15))domain

\frac{x ^{2} + 5 x + 6}{x + 15}

range of f(x)=x^2-6x+13 range

f (x) = x^{2} - 6 x + 13

domain of f(x)= 1/(sqrt(|x^2-5x+6|))domain

f (x) = \frac{1}{∣ x ^{2} - 5 x + 6 ∣}

domain of f(x)= 1/(2x+4)domain

f (x) = \frac{1}{2 x + 4}

domain of (2x^2+10x+12)/(x^2+2x-3)domain

\frac{2 x ^{2} + 10 x + 12}{x ^{2} + 2 x - 3}
