The path of a football after being kicked can be modeled by the function f(x) = -169 (2 – 65) 2 + 25 where x represents the horizontal distance the football
169
travels in feet and f(x) represents the vertical distance of the football. How far does the
football travel after being kicked?
O 169 feet
130 feet
O 30 feet
0 25 feet

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
