1. (4 pts) Which of these graphs of relations describe y as a function of x? That is, which are graphs of functions?Answer(s): ____________ (no explanation required.)(There may be more than one graph which represents a function.) (A) (B) (C) (D) 2. (10 pts) Consider the points (–5, –6) and (–1, 10). (a) State the midpoint of the line segment with the given endpoints. (No work required) (b) If the point you found in (a) is the center of a circle, and the other two points are points on the circle, find the length of the radius of the circle. (That is, find the distance between the center point and a point on the circle.) Find the exact answer and simplify as much as possible. Show work.
