Answer:
3rd [-5,7)
Step-by-step explanation:
[-5,7) is the right answer because check the restrictions on both of the functions given in the piecewise function, it only exists between -5 and 7 where, the -5 is included, hence the Square bracket! And 7 is not included, hence the round bracket! Therefore, your answer is [-5,7).
