Applying the intermediate value theorem
Suppose f is a continuous function on [-2, 2] such that f(-2)=1, f(2)= -1?
Which of the properties below follow without further restriction on f by applying the Intermediate Value Theorem?
A) f^2 (c) is 1/4 for some C in (-2,2)
B) f(x)+1 > or = o (-2,2)
C) f(c)=0 for some c in (-1,1)
