f(x)=9x^2+8x-40

Solution

f (x) = 9 x^{2} + 8 x - 40

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{376}{9}

X Intercepts : (\frac{2 ( 94 - 2 )}{9}, 0), (- \frac{2 ( 2 + 94 )}{9}, 0), Y Intercepts : (0, - 40)

Vertex : Minimum (- \frac{4}{9}, - \frac{376}{9})

Inverse : \frac{- 4 + 9 x + 376}{9}, - \frac{9 x + 376 + 4}{9}
