Algebra 1 Embedded Assessment 1 Unit 5, page 453 Name ____________________________ Parabolic Paths In 1680, Isaac Newton, scientist, astronomer, and mathematician, used a comet visible from Earth to prove that some comets follow a parabolic path through space as they travel around the sun. This and other discoveries like it help scientists to predict past and future positions of comets. 1. Assume the path of a comet is given by the function π¦ = βπ₯ ! + 4. a. Graph the path of the comet. Explain how you graphed it. b. Identify the vertex of the function. c. Identify the maximum or minimum of the function. d. Identify the domain and range. e. Write the equation for the axis of symmetry. 2. Identify the table that represents a parabolic comet path. Explain why and justify your choice. 3. The graph at the right shows a portion of the path of a comet represented by a function in the form π¦ = (π₯ β β)! + π. a. Write the equation of the function. b. Simplify your equation and rewrite in standard form. 4. The equation and graph below represent two different quadratic functions for the parabolic paths of comets. Identify the maximum of each function. Which function has the greater maximum value? Function 1: Function 2: π¦ = βπ₯ ! + 4 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
