Answer:
Domian x is set of all real numbers (-∞, ∞)
range is U [2,∞)
Step-by-step explanation:
A. Graph the piece-defined function
f(x)={x+4,x≥-2
-6, x<-2
Domain is the set of x values,
Domian x is set of all real numbers
For range we check the y values
Plug in for x
so range is y values greater than 2
For second function, y value is only -6
So range is U [2,∞)
