Question 50756: 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}.
