f(x)=-0.9x^2+1.7x+2.5

Solution

f (x) = - 0.9 x^{2} + 1.7 x + 2.5

Solution

Domain : - \infty < x < \infty

Range : f (x) \leq 3.30277 \dots

X Intercepts : (- \frac{- 17 + 1189}{18}, 0), (\frac{17 + 1189}{18}, 0), Y Intercepts : (0, 2.5)

Vertex : Maximum (0.94444 \dots, 3.30277 \dots)

Inverse : - \frac{- 17 + - 360 x + 1189}{18}, - \frac{- 17 - - 360 x + 1189}{18}
