Answer:
p(x) = x(x+2).
Step-by-step explanation:
From the graph , the zeroes are -2 and 0 so we can write it as
P(x) = ax(x + 2) where a is some constant.
We also see from the graph that when x = -1, p(x) -1 so substituting for these values:
-1 = a(-1)(-1+ 2)
-1 = a(-1)(1)
-a = -1
so a = 1
So p(x) = x(x+2).
