Provide an appropriate response.Prove that the function f is not one-to-one.f(x) = 
- 2
What will be an ideal response?
Answers may vary. Possible answer:
Find two numbers a and b for which a ? b and f(a) = f(b). Two such numbers are -3 and 3 because f(-3) = f(3) = 1. Thus, f is not one-to-one.

Solve the problem or provide an explanation.Graph y = -x2 + 5x + 6 and f(x) = 
together on your graphing calculator. State the domain of f(x) and explain the connection between the domain of f(x) and the graph of 
A. The domain of f(x) is (-?, ?). The domain of f(x) is the same as the domain of y = -x2 + 5x + 6.
B. The domain of f(x) is (-?, -1] ? [6, ?). The domain of f(x) is the set of all x-values for which the graph of
