inverse of f(x)=2x^2-12x+13,x<= 1

inverse

f (x) = 2 x^{2} - 12 x + 13, x \leq 1

\frac{12 + 8 x + 40}{4}, \frac{12 - 8 x + 40}{4}

Solution steps

y = 2 x^{2} - 12 x + 13

Replace

x

with

y

x = 2 y^{2} - 12 y + 13

Solve for

y, x = 2 y^{2} - 12 y + 13

\frac{12 + 8 x + 40}{4}, \frac{12 - 8 x + 40}{4}
