Y(x)=x^2-7x+8

Solution

Y (x) = x^{2} - 7 x + 8

Solution

Domain : - \infty < x < \infty

Range : f (x) \geq - \frac{17}{4}

X Intercepts : (\frac{7 + 17}{2}, 0), (\frac{7 - 17}{2}, 0), Y Intercepts : (0, 8)

Vertex : Minimum (\frac{7}{2}, - \frac{17}{4})

Inverse : \frac{7 + 4 x + 17}{2}, \frac{7 - 4 x + 17}{2}
