To analyze the equation $y = 2(x - 1)(x + 2)$, we can expand it to better understand its characteristics.

1. Expanding the equation: $y = 2(x - 1)(x + 2)$ $= 2[(x)(x) + (2x) - (1x) - (2)]$ $= 2(x^2 + x - 2)$ $= 2x^2 + 2x - 4$

2. Characteristics:

   • Type: This is a quadratic equation (a parabola).
   • Vertex: The vertex can be found using the formula $x = -\frac{b}{2a}$: $x = -\frac{2}{2 \cdot 2} = -\frac{1}{2}$
   • Y-intercept: Set $x = 0$: $y = 2(0 - 1)(0 + 2) = 2(-1)(2) = -4$
   • X-intercepts: Set $y = 0$: $0 = 2(x - 1)(x + 2)$ The x-intercepts are $x = 1$ and $x = -2$.

3. Graph: The parabola opens upwards (since the coefficient of $x^2$ is positive).
