inverse of f(x)=15+3sqrt(x)

inverse

f (x) = 15 + 3 x

\frac{x ^{2}}{9} - \frac{10 x}{3} + 25

Solution steps

y = 15 + 3 x

Replace

x

with

y

x = 15 + 3 y

Solve for

y, x = 15 + 3 y

\frac{x ^{2}}{9} - \frac{10 x}{3} + 25

f (x) = x^{2} - 1, x \geq 1

y = \frac{1}{x - 3}

f (x) = 0.5 (1 - e^{2 x})

f (x) = lo g_{2} (x + 7)

y = 2 (3 x + 1) + 4
