Determine Whether the Graph Is That of a Function

question 57

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: {y|y > 0} Intercept: (1, 0) Symmetry: none
• B) function domain: {x|x > 0} range: all real numbers intercept: (0, 1) symmetry: origin
• C) function domain: {x|x > 0} Range: all real numbers Intercept: (1, 0) Symmetry: none
• D) not a function
