A net force with x-component F x acts on an object from time t 1 to time

Question:

A net force with x-component ΣF_x acts on an object from time t₁ to time t₂. The x-component of the momentum of the object is the same at t₁ as it is at t₂, but ΣF_x is not zero at all times between t₁ and t₂ . What can you say about the graph of ΣF_x versus t?
