Use polynomial graph shape and end behavior to determine which of the following could be the x-coordinates at which the relative
maximum and relative minimum occur in the given function.
f(x) = -10x^3+6x-2

The triangles are similar. what is the value of x? show your work.

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.

What is the value of x? enter your answer in the box. x =
