Answer:
(a) upward
(b) (-2, -4)
(c) -2 = x
(d) x-intercept(s): (-6, 0), (2, 0)
y-intercept: (0, -3)
Step-by-step explanation:
(a) It clearly opens up at a minimum point of -4.
(b) It is the centre point of your parabola.
(c) Take the x-coordinate of your vertex and set it equal to <em>x</em><em>.</em>
(d) X-intercepts [Zeros, or roots] are where they intersect the x-axis on both ends of the parabola, and according to the graph, they intersect the x-axis at <em>the</em><em> </em><em>above</em><em> </em><em>answers</em><em>.</em>
