#### Answer:

#### Explanation:

Let us name the Intervals

On these Intervals

are continuous on these intervals.

So, if

has to be continuous at the joining points of these intervals; i.e., to

say, it must be continuous at

Now, for continuity at

On the similar lines, we have,

Considering the continuity of

Solving
