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

inverse

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

- 2 + x + 2, - x + 2 - 2

Solution steps

y = x^{2} + 4 x + 2

Replace

x

with

y

x = y^{2} + 4 y + 2

Solve for

y, x = y^{2} + 4 y + 2

- 2 + x + 2, - x + 2 - 2

2 e^{3 x}

\frac{1}{x - 6}

g (x) = 2 (x - 1)^{2} - 3

2 cos (4 x - π)

f (x) = 2 x^{2} - 8 x + 5
