Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. x4 + x − 7 = 0, (1, 2) f(x) = x4 + x − 7 is ---Select--- on the closed interval [1, 2], f(1) = , and f(2) = . Since −5 < ? < 11, there is a number c in (1, 2) such that f(c) = ? by the Intermediate Value Theorem. Thus, there is a ---Select--- of the equation x4 + x − 7 = 0 in the interval (1, 2).

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
