Attached you will see the solution using the trig plane and general solutions.
It depends really. If you stay close to the present, then predicting future results isn't too bad. The further you go out, the more unpredictable things get. This is because the points may deviate from the line of best fit (aka regression line) as time wears on. Of course, it also depends on what kind of data we're working with. Some pairs of variables are naturally going to correlate very strongly together. An example would be temperature versus ice cream sales.
Answer:
To make f continuous at
,
should be defined 
Step-by-step explanation:
A function, let say
, is defined at
is continuous at 
If the limit of
as
approaches
is equal to the value of
at
.
Mathematically it is written as:
if

then
is continuous at
.
So from the above definition, we conclude that:
To make f continuous at
,
should be defined 
i.e.
if

then
is continuous at
.
