Graph the function y = x3 + 3x2 – X-3. Which lists all of the turning points of the graph rounded to the nearest whole number?
O(-3,0) and (1,0)
O (-2, 3) and (0, -3)
O (-2, 3), (-1,0), and (0, -3)
O (-3,0), (-1,0), and (1,0)

D (The 4th one)

Step-by-step explanation:

as you can see, the x intercept is (−3,0),(−1,0),(1,0)

and y's is (0,−3)

Hope this helps ;)

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.
