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

Solution

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

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{13}{4}

X Intercepts : (\frac{7 + 13}{2}, 0), (\frac{7 - 13}{2}, 0), Y Intercepts : (0, 9)

Vertex : Minimum (\frac{7}{2}, - \frac{13}{4})

Inverse : \frac{7 + 4 x + 13}{2}, \frac{7 - 4 x + 13}{2}
