inverse of f(x)=2x+1f(x)=x^2+4

inverse

f (x) = 2 x + 1 f (x) = x^{2} + 4

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

f (x) = x + 6 + 1

f (x) = \frac{8 x}{5 x - 4}

f (x) = - 5 x - 3 + 4

f (x) = \frac{1}{y}

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