can identify the vertex for each parabola:
For f(x), the vertex is at (3, 4).
• For g(x), the vertex is at (−1, 7).

vertex for each function. For f(x), plot the
point (3, 4), and for g(x), plot the point (-1, 7).
5. Determine the Direction of Opening: Look at
the "a" value in each equation. If "a" is positive,
the parabola opens upward; if "a" is negative,
it opens downward.
For f(x), with a = 2, the parabola opens
upward.
• For g(x), with a = -1, the parabola
opens downward.
