I did not understand the Intermediate Value Theorem explained today in class. The professor did not even go to his office hours :(. Use the intermediate Value to show that there is a root of the given equation in the specified interval. #51 in Stewart's Calculus 7th ed. (section 1.8) x^4 + x - 3=0 What I know so far. the equation or function has to be continuous throughout the given interval. ie (0,2) so f(0)<c<f(1) we plug in the x's into the equation and get the Y values then we compare them. my problem is i do not understand the computation. Can someone please give me a step by step approach the problem? Thanks.
