1. Part A : Determine the domain and range of the function in the graph. 2. Part B: is the function one-to-one? Why or why not?
A. The function is one-to-one because for every input value there is exactly one output value.
B. The function is one-to-one because no horizontal line would intersect the graph of the function more than once.
C. The function is not one-to-one because for every input value there is exactly one output value.
D. The function is not one-to-one because there exists a horizontal line that would intersect the graph of the function more than once.
