Solution: Since f is defined for all real values of x, the domain is the set of all real numbers. In
the interval (, 2), the graph of f is a parabola shifted up 1 unit. In addition, this interval is
open at x = 2 and therefore the graph shows an “open point” on the graph at x = 2. In the interval
[2, ), the graph is a line with an x-intercept at (3,
