Determine Whether the Graph Is That of a Function

question 96

Multiple Choice

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|-2 ≤ x ≤2} Range: all real numbers Intercepts: (-2, 0), (2, 0) Symmetry: x-axis, y-axis
• B) function domain: all real numbers range: {y|y ≤-2 or y ≥ 2} intercepts: (-2, 0), (2, 0) symmetry: y-axis
• C) function domain: {x|x ≤-2 or x ≥ 2} Range: all real numbers Intercepts: (-2, 0), (2, 0) Symmetry: x-axis, y-axis, origin
• D) not a function
