ANSWER:
(a) downwards
(b) (2, 0)
(c) x-intercept: (2,0), y-intercept: (0,-4)
(d) x = 2
STEP-BY-STEP EXPLANATION:
(a)
We can see that the parabola opens downwards since it has a maximum value.
(b)
The vertex is the maximum point in this case, we can identify it in the graph and it would be: (2, 0)
(c)
The intercepts are the points where each intercept passes, the x-intercept is (2,0) and the y-intercept is (0,-4)
(d)
The axis of symmetry is x = 2, since it is the point that divides the graph into two equal or symmetrical parts.
We identify each point on the following graph:
