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|-1 ? x ? 1} range: all real numbers intercepts: (-1, 0), (1, 0) symmetry: x-axis, y-axis B. function domain: {x|x ? -1 or x ? 1} range: all real numbers intercepts: (-1, 0), (1, 0) symmetry: x-axis, y-axis, origin C. function domain: all real numbers range: {y|y ? -1 or y ? 1} intercepts: (-1, 0), (1, 0) symmetry: y-axis D. not a function
Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 - 16x + 14y + 113 = 16
A. (x - 8)2 + (y + 7)2 = 16 center (8, -7), r = 4 B. (x - 8)2 + (y + 7)2 = 16 center (8, -7), r = 16 C. (x + 7)2 + (y - 8)2 = 16 center (-7, 8), r = 4 D. (x + 8)2 + (y - 7)2 = 16 center (-8, 7), r = 16
