inverse of f(x)=x^2+2x+111

inverse

f (x) = x^{2} + 2 x + 111

- 1 + x - 110, - x - 110 - 1

Solution steps

y = x^{2} + 2 x + 111

Replace

x

with

y

x = y^{2} + 2 y + 111

Solve for

y, x = y^{2} + 2 y + 111

- 1 + x - 110, - x - 110 - 1

f (x) = 5 x^{2} - 39

f (x) = (\frac{1}{8}) x^{2} + 2 x + 7

f (x) = - 4 x^{9} - 4

f (x) = 5 x^{2} - 42

f (x) = f (x) = x^{3} - 7
