d)
In order to find where f(x) = -3, we need to look at the graph for the values of x where y = -3.
Looking at the graph, when y = -3, x can be any value on this interval:
[tex]x=[0,1)[/tex]
(That is, x can assume any value between 0 and 1, including 0).
Therefore the answer is [0, 1).
e)
The x-intercepts are the points where the graph intersects the x-axis.
Looking at the graph, it only intersects the x-axis at one ordered pair: (-1, 0).
