Quick Answer
Para \( f(x) = 2x^2 - 3x \):
- Puntos de corte en el eje \( x \): \( (0, 0) \) y \( \left(\frac{3}{2}, 0\right) \)
- Vértice: \( \left(\frac{3}{4}, -\frac{9}{8}\right) \)
Para \( g(x) = 6x^2 + 9x - 2 \):
- Puntos de corte en el eje \( x \): \( x_1 = \frac{-9 + \sqrt{129}}{12} \) y \( x_2 = \frac{-9 - \sqrt{129}}{12} \)
- Vértice: \( \left(-\frac{3}{4}, -\frac{43}{8}\right) \)
