Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if any, and any symmetry with respect to the x-axis, the y-axis, or the origin.
A. function
domain: {x|-9 ? x ? 9}
range: {y|-9 ? y ? 9}
intercepts: (-9, 0), (0, -9), (0, 0), (0, 9), (9, 0)
symmetry: origin
B. function
domain: {x|-9 ? x ? 9}
range: {y|-9 ? y ? 9}
intercepts: (-9, 0), (0, -9), (0, 9), (9, 0)
symmetry: x-axis, y-axis
C. function
domain: {x|-9 ? x ? 9}
range: {y|-9 ? y ? 9}
intercepts: (-9, 0), (0, -9), (0, 9), (9, 0)
symmetry: x-axis, y-axis, origin

Answer the following statement(s) true (T) or false (F)
1. Any angle inscribed in a semicircle must be a right angle.
2. If the central angle of a sector with radius 10" measures 60°, then the area of the sector is 5/3? square inches.
3. The measure of an inscribed angle, ?A, in a circle is twice the measure of a second inscribed
angle, ?B, in the same circle. Then the arc intercepted by ?A is twice as long as the arc intercepted by ?B.
4. If P is the midpoint of chord AB in circle O, then ?OPB = 90°.
5. If two chords in circle O, MN and XY, intersect at P then ?MPX =
