A toy rocket launch can be represented by a parabolic function. Your most recent launch for the science fair can be modeled by the function y = -4(x – 5)^2 + 125 where Y is the height of the rocket and X is the number of seconds since launch. Graph this function and include all of the points listed above, then discuss in context what the vertex and x-intercepts mean in context. 1. your graph and the method of graphing shown and reasoning discussed
2. labeled key features
3. domain and range
4.interpret the vertex
5.interpret solutions
