Exercise 7.5.6: Prove the following version of the intermediate value theorem. Let (𝑋 , 𝑑) be a connected metric space and 𝑓 : 𝑋 -> R a continuous function. Suppose 𝑥0, 𝑥1 in 𝑋 and 𝑦 in R are suchExercise 7.5.6: Prove the following version of the intermediate value theorem. Let (x,d) be a connected
metric space and f:x->R a continuous function. Suppose x_(0),x_(1)inx and yinR are such that
zinxf(z)=yf(x_(0)). Then prove that there exists a zinx such that f(z)=y. Hint: See Exercise 7.5.5.
Exercise 7.5.6: Prove the following version of the intermediate value theorem. Let (X, d) be a connected metric space and f: X , R a continuous function. Suppose xo,x1 e X and y e R are such that f(xo) < y < f(x1). Then prove that there exists a z e X such that f(z) = y. Hint: See Exercise 7.5.5.
