Describe the possible numbers of intersections for each of the following pairs of graphs. Sketch a graph for each possibility. For example, a circle could intersect a line twice, once, or not at all. Your solution to each part should include all of the possibilities and a sketched example of each one.

  1. Two different lines.

    0, 1, or ∞

  1. A line and a parabola.

    0, 1 or 2

  1. Two different parabolas.
