SOLUTION: Determine whether the set T= {( �2, �8), (�1, �1), (0, 0), (�1, 1), (�2, 8)} defines a function. If it does, then state the domain and range. a. T does not define a function

Question 50963: Determine whether the set T= {( �2, �8), (�1, �1), (0, 0), (�1, 1), (�2, 8)} defines a function. If it does, then state the domain and range.
a. T does not define a function.
b. T defines a function with domain { �2, �1, 0} and range { �8, �1, 0, 1, 8}.
c. T defines a function with domain { �8, �1, 0, 1, 8} and range { �2, �1, 0}.
d. T defines a function with domain {( �2, �8), (�1, �1), (0, 0), (�1, 1), (�2, 8)} and range { �2, �1, 0}.
