2-66.

Using set notation, state the domain and range for each of the functions below. 

  1. Upward V, vertex at the point (1, comma 1), passing through the point (0, comma 2).

  1. Increasing curve, opening down, starting at the point (negative 3, comma negative 2), passing through the y axis between 1 & 2, continuing up & right.

Piecewise graph, left piece, upward parabola, vertex at about (0.5, comma 1), starting at closed point (0 comma 3), & ending at open point (1, comma 3), center piece, downward parabola, vertex at about ((1.5, comma 5), starting at open point (1, comma 3), ending at open point (2, comma 3), right piece, increasing curve, opening down, starting at closed point (2, comma 1), with open point on the curve at (3, comma 2), & a discrete point not on the curve, at (3, comma 3).Domain and Range

There are two accepted forms of notation for domain and range. Examine the graph at right. The domain and range of the function shown can be noted in either interval notation or in set notation.
