f(x)=7x^2-9x-5

Solution

f (x) = 7 x^{2} - 9 x - 5

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{221}{28}

X Intercepts : (\frac{9 + 221}{14}, 0), (\frac{9 - 221}{14}, 0), Y Intercepts : (0, - 5)

Vertex : Minimum (\frac{9}{14}, - \frac{221}{28})

Inverse : \frac{9 + 28 x + 221}{14}, \frac{9 - 28 x + 221}{14}
