Answer:
Left side
Ca(OH)2 --> Ca + 2 O + 2 H
2 HBr --> 2 H + 2 Br
Together: Ca + 2 O + 4 H + 2 Br
You have only 1 Br and only 3 H. So you must correct this.
The best estimate would be in the two thousands
The actual answer is 2023

y=2


Explanation
Step 1
The y -intercept of a graph is the point where the graph crosses the y -axis.
so , let's check the graph
therefore, the y-intercept is 2
Step 2
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)
hence, the function is potive in ( in x axis)

Step 3
negative region
The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

I hope this helps you
