Provide an appropriate response.Explain why the function f(x) = (x - 1)2 + 7 is not a one-to-one function.
What will be an ideal response?
Answers will vary. If you graph f, note that the graph is a parabola opening up which does not pass the horizontal line test. Considering the set of ordered pairs associated with f, for each second component there is not exactly one first component.
