Determine whether the graph on the right is that of a function by using the vertical-line
test. If it is, use the graph to find the following.
(a) the domain and range (assume that the curve approaches but never intersects
the y-axis)
(b) the intercepts, if any
(c) any symmetry with respect to the x-axis, y-axis, or the origin
A. No, the graph is not a function because a vertical line x = 2 intersects the graph at two points.
B. No, the graph is not a function because a vertical line x = 2 intersects the graph at only one point.
C. Yes, the graph is a function because every vertical line intersects the graph in at most one point.
D. Yes, the graph is a function because every vertical line intersects the graph in more than one point.
(a) What are the domain and range of the function? Select the correct choice below and, if necessary, fill in the
answer box(es) to complete your choice.
A. The domain is. The range is
(Type your answers in interval notation. Use integers or fractions for any numbers in the expressions.)
B. The graph is not that of a function.
