Determine Whether the Graph Is That of a Function

question 13

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|-7 ≤ x ≤7} Range: {y|-7 ≤ y ≤ 7} Intercepts: (-7, 0), (0, -7), (0, 0), (0, 7), (7, 0) Symmetry: origin
• B) function domain: {x|-7 ≤ x ≤7} range: {y|-7 ≤ y ≤ 7} intercepts: (-7, 0), (0, -7), (0, 7), (7, 0) symmetry: x-axis, y-axis, origin
• C) function domain: {x|-7 ≤ x ≤7} Range: {y|-7 ≤ y ≤ 7} Intercepts: (-7, 0), (0, -7), (0, 7), (7, 0) Symmetry: x-axis, y-axis
• D) not a function
