Domain is the entire span left to right (on the x-axis) that the graph is on. Since the graph goes from x=-4 and ends at x=4, the domain would be from -4 to 4. The circle at -4 is open, so it does not include the point at -4, just everything leading up to it. So, the domain would be
The range is similar, it is the entire span that the graph goes up and down (on the y-axis). The graph starts at the bottom at y=-2, and ends at y=5. The bottom point (4,-2) is closed, so the graph includes that point, and the top point (-4,5) is open and doesn't include the point. Therefore, the range would be

is the Square Root Function. These are the characteristics of the graph of the square root function:
- The domain of the function is the set of all non negative real numbers.
- The range of the function is the set of all non negative real numbers.
-
The graph has an intercept at
.
-
The graph is increasing on the interval
.
Since the function , then this stands for the form:
. This form tells us that the graph of f has been shifted c units downward where the value c = 2 in this problem. The graphs of both functions are shown below. The red one is
