inverse of 4sqrt(x)-x

inverse

4 x - x

- x + 8 + 4 - x + 4, - x + 8 - 4 - x + 4

Solution steps

y = 4 x - x

Replace

x

with

y

x = 4 y - y

Solve for

y, x = 4 y - y

- x + 8 + 4 - x + 4, - x + 8 - 4 - x + 4

y = 9 x - 9

f (x) = - 6 (x + 7)

f (x) = \frac{( x + 3 )}{( x - 1 )}

x + 1 - 2

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