Answer 1

a) since value of f(x) represents height, the x-intercepts are when height is 0, and the maximum is the maximum height. as for the intervals, you just need to identify over which x values the graph is increasing, and the x-values where the graph is decreasing

Answer 2

*** as for the intervals, you just need to identify over which x values the graph is increasing, and the x-values where the graph is decreasing ***
