Why not just work for 50 hrs on house cleaning and get 1000$
X= 9 1/4 or 9.25 in decimal form

Answer:
The last one.
Step-by-step explanation:
The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.
The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.
Hence the last graph is the correct one.
