The path of a particle is modeled by the function x) - - 210,:2 + 4x + 9, where x) is the height (in feet) of the particle and x is the horizontal distance (In feet) From where the particle started moving. {a} What is the maximum height (in ft) of the particle? |:l (b) Which number determines the height at which the particle started moving? |:| Does changing this value change the coordinates of the maximum height of the particle? Explain. 0 Yes, changing this value results in both a vertical and a horizontal shift of the graph, so the maximum height changes. 0 Yes, changing this value results in a vertical shi of the graph, so the maximum height changes. 0 No, changing this value does not shift the graph, so the maximum height does not change. 0 No, changing this value results In a horizontal shi of the graph, so the maximum height does not change
