f(x)=x^2+11x-18

Solution

f (x) = x^{2} + 11 x - 18

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{193}{4}

X Intercepts : (\frac{- 11 + 193}{2}, 0), (\frac{- 11 - 193}{2}, 0), Y Intercepts : (0, - 18)

Vertex : Minimum (- \frac{11}{2}, - \frac{193}{4})

Inverse : \frac{- 11 + 4 x + 193}{2}, \frac{- 11 - 4 x + 193}{2}
