Hey I need some help finding net income. Can you verify if my answers are correct. Is it net loss or net income?

Shep Company's records show the following information for the current year. Determine net income (loss) for each of the following separate situations. Note: For all requirements, losses should be entered with a minus sign. a. Additional owner investments of $3,400 were contributed, and withdrawals of $7,400 were made during the current year. b. Additional owner investments of $15,100 were contributed, and no withdrawals were made during the current year. c. No additional owner investments were contributed, and withdrawals of $12,400 were made during the current year
