Use the Intermediate Value Theorem to determine the existence of a solution to f(x) = V on the interval [a, b].

Let /(x) =x2-4x on [5, 8] . Use the IVT to determine if there is a solution to /(*) =21 in the interval between 5 and 8. If so, find the value of c in the interval such that /(c) = 21 . a.) . f(x) is continuous on [5, 8] O . 21 is between /(5) =5 and /(8) = 32 . C= 357 b.) . f(x) is continuous on [5, 8] O . 21 is between /(5) =5 and /(8) = 32 C =7 C.) . f(x) is continuous on [5, 8] O . 21 is between /(5) =5 and /(8) =32 . 0= -3 ,0=7 d.) . f(x) is continuous on [5, 8] O . 21 is not between 5 and 8 so the IVT does not apply
