(a)The domain is the set of values of x in the function.
From the graph, the domain of f(x) is: (-∞, ∞)
(b)The range is the set of values of y in the function.
From the graph, the range of f(x) is: (0, ∞)
(c)From the graph, When x=-3, y=0
Therefore: f(-3)=0
(d)There is no value of x that gives f(x)=-2.
The values of x for which f(x) =-2 is Undefined.
(e)The point where the graph of f crosses the x-axis is (0, 0).
(f)The point where the graph of f crosses the y-axis is (0, 0).
(g)The value of f(x) is not negative. Therefore, the value of x for which f(x) < 0 is Undefined.
(h)When x=-8, f(x)=0
Therefore, f(-8) is zero. It is neither positive nor negative.
