1 2 Let f(x) = - x2 + 7x on [4, 9]. Use the IVT to determine if there is a solution to f(x) = 10 in the interval between 4 and 9. If so, find the value of c in the interval such that f(c) = 10. . f(x) is continuous on [4, 9] O . 10 is between f(4) = 12 and f(9) = - 18 c = 2 . f(x) is continuous on [4, 9] O . 10 is between f(4) = 12 and f(9) = - 18 . C =2, c=5 . f(x) is continuous on [4, 9] O . 10 is not between 4 and 9 so the IVT does not apply f(x) is continuous on [4, 9] O 10 is between f(4) = 12 and /(9) = - 18 C = 5 64 F Mostly
