Question

If the cubic function P(x) includes the points (−4, 0), (0, 0), and (2, 0), which of the following represents this function?

Answer 1

We observe that the function has the following behavior:
 x y
 -4 0
 0 0
 2 0
 Therefore, the function that best suits this behavior is:
 P (x) = 0
 This function is the same as a horizontal line along the entire x axis.
 Answer:
 P (x) = 0
 Horizontal line along the x axis.
