Step-by-step explanation:
(x,y)
x represents the x co-ordinate of a point
y represents the y co-ordinate of a point
Answer:
a) The domain is the set of the possible values of x.
In the graph, we can see that x goes from - 4 to 4
So the domain is: D = x∈ {-4, 4)
b) The zeros are the points where the graph cuts the x-axis.
Those values are:
x = -2
x = 0
x = 2.
c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.
in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.
in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.
in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
