1-107.

What is the domain and range of each function graphed below?

See problem 1-98 for help.

  1. Curved graph, with 2 decreasing sections and asymptotes at, x axis, &, y axis. Left section: as x values get more negative, y's approach, x axis from below, & as x values approach y axis, from left side, y values decrease rapidly, Right section: as x values approach, y axis, from right side, y values increase rapidly, &, as, x values get bigger, y's approach, x axis from above.

    Are there any asymptotes?

  1. Line segment, from open point at (negative 5, comma negative 4) to closed point, (6, comma 2)

    D:
    R:

  1. Downward parabola with vertex at (2, comma 1), passing through the points (0, comma negative 1).

    See hint above.
