Describe the piecewise function below by evaluating the function for given values of the domain
tekilochka [14]
We have a piecewise function.
 Therefore, to find the function, we must evaluate each domain separately.
 We have then:

 For x  \leq  -2:
 The function for this domain is:
 y = -3


 
For -2 \ \textless \  x  \leq  2:
 
The function for this domain is:
 y = mx + b

 Where,
 b = -3

 m = (y2 - y1) / (x2 - x1)

 m = (1 - (-7)) / (2 - (-2))
 m = (1 + 7) / (2 + 2)

 m = 8/4

 m = 2
 Substituting:
 y = 2x - 3


 
For x\ \textgreater \  2:
 
The function for this domain is:
 y = 5
