Answer:
The last one
Step-by-step explanation:
The zeros of a function f(x) are the values of x such that f(x)=0. Since the coordinate y equals f(x), we must look for the values where y=0 (x-intersect).
Since f(x) is factorized, f(x)=0 only when one of its factors equals zero.
So we have
f(x) = 0 ===> x+2 = 0 OR x+1 = 0 OR x+4 = 0
and we have
x = -2 or x = -1 or x = -4
Hence the function must intersect the x-axis at these points.
The only graph that matches the requirements is the last one.
