Provide an appropriate response.Prove that the function f is not one-to-one.f(x) = 2 - x4
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 -2 and 2 because f(-2) = f(2) = -14. Thus, f is not one-to-one.
