Greetings from Brasil...

Here we have a piecewise function, because for each interval there is a specific function.

Looking at the graph and remembering the concepts of constant function and linear function, we can conclude that:

a:

F(X) = - 2

.......................................................

b:

F: {2} → {- 1}

.......................................................

c:

F(X) = 2X - 8

.......................................................

Then we conclude that

F(- 2) = - 2

need to check the attachment

__________________________________

The function F(X) in question is not continuous at X =2

Piecewise Function

Sometimes a function may not be defined uniformly throughout its domain. It may be defined in two or more ways as its domain is split into two or more parts.
