Vlad is playing on a swing set.
His horizontal distance D(t) in m) from the center where being behind the center means a negative distance
as a function of time t (in seconds) can be modeled by a sinusoidal expression of the form a-cost-t) +
Att = 0, when he pushes off, he is 1 m behind the center, which is as far back as he goes. The shing reaches
the center - seconds later,

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
