y=x^2+9x-4

Solution

y = x^{2} + 9 x - 4

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{97}{4}

X Intercepts : (\frac{- 9 + 97}{2}, 0), (\frac{- 9 - 97}{2}, 0), Y Intercepts : (0, - 4)

Vertex : Minimum (- \frac{9}{2}, - \frac{97}{4})

Inverse : \frac{- 9 + 4 x + 97}{2}, \frac{- 9 - 4 x + 97}{2}
