inverse of 5(sqrt(x)+5)-9

inverse

5 (x + 5) - 9

\frac{x ^{2}}{25} - \frac{32 x}{25} + \frac{256}{25}

Solution steps

y = 5 (x + 5) - 9

Replace

x

with

y

x = 5 (y + 5) - 9

Solve for

y, x = 5 (y + 5) - 9

\frac{x ^{2}}{25} - \frac{32 x}{25} + \frac{256}{25}

\frac{5 - x}{x ( x - 4 )}

y = - \frac{1}{7} x - 4

y = x + 8

f (x) = (2 x + 5)^{3} - 6

f (x) = 2 x^{2} - 8 x + 9
