inverse of f(x)=4sqrt(x)+x

inverse

f (x) = 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

f (x) = 15 x^{2} - 38

f (x) = 20 cos (5 x + 7)

f (x) = (- 12 x - 17)^{2}

\frac{2}{s - 3}

\frac{( x ^{2} )}{4 x}
