Good evening Guest!
How do i find a formula for the inverse
if this is one to one x - 10 /x + 4
y = x - \(\frac{10}{x} \) + 4
Inverse
x = y - \(\frac{10}{y} \) + 4
xy = y² - 10 + 4y
y² - 10 + 4y - xy = 0
y² + (4 - x) y - 10 = 0
Quadratic formula
\(y = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
a = 1 b = (4 - x) c = - 10
