the 4 on the sides are half the area of the ones of the top and bottom because if you take two small ones they will fit with one of the big ones.
sorry if I'm wrong.
Answer:
not existing
Step-by-step explanation:

lim x goes to 0 is

so not exist
I'm not sure if u mean that or this
Answer:
(-16, 0) and (0,-12) are exactly two points on the graph of the given equation.
Step-by-step explanation:
Here, the given expression is : 
Here, let M(a) = b
⇒The equation becomes 
Now, check for all the given points for (a,b)
<u>1) FOR (-9,0)</u>

Hence, (-9,0) is NOT on the graph.
<u>2) FOR (-16,0)</u>
Here, LHS = b = 0
and
Hence, LHS = RHS = 0 So, (-16,0) is on the graph.
<u>3) FOR (0,12)</u>
Here, LHS = b = 12

Hence, (0,12) is NOT on the graph.
<u>4) FOR (0,-12)</u>
Here, LHS = b = -12

and LHS = RHS = -12
Hence, (0,-12) is on the graph.
Hence, (-16, 0) and (0,-12) are exactly two points on the graph of the given equation.
