Determine Whether the Graph Is That of a Function

question 148

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: all real numbers Range: all real numbers Intercept: (0, -4) Symmetry: none
• B) function domain: all real numbers range: {y|y = 5 or y = -4} intercept: (0, -4) symmetry: none
• C) function domain: {x|x = 5 or x = -4} Range: all real numbers Intercept: (-4, 0) Symmetry: x-axis
• D) not a function
