I need help with this

Answer:
ƒ(x) = (x - 1)(x - 2)(x - 3)
Step-by-step explanation:
The graph shown is that of a cubic equation with zeros at x = 1, 2, and 3
The function in factored form must be
ƒ(x) = (x - 1)(x - 2)(x - 3).
When you solve for the zeros, the sign of the constant changes. For example
x - 1 = 0
x = 1
