inverse of f(x)=-3sqrt(4x+8)

inverse

f (x) = - 3 4 x + 8

\frac{x ^{2} - 72}{36}

Solution steps

y = - 3 4 x + 8

Replace

x

with

y

x = - 3 4 y + 8

Solve for

y, x = - 3 4 y + 8

\frac{x ^{2} - 72}{36}

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

f (x) = (x - 3)^{2} - 2

f (x) = (x + 10)^{3}

w (t) = 80 - 2.5 t

2 \cdot 3^{x} + 9^{x} + 5
