Answer:
A. see the attached
B. domain: all real numbers; range: [-6, -6] U [2, ∞)
Step-by-step explanation:
A. The graph is shown in the attachment.
__
B. The function is defined for all values of x, so the domain is all real numbers.
The range includes all numbers 2 or greater, as well as -6.
Answer:
Domian x is set of all real numbers (-∞, ∞)
range is [tex](-6)[/tex] 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, [tex]x\geq -2, x<-2[/tex]
Domian x is set of all real numbers
For range we check the y values
[tex]y=x+4[/tex]
Plug in [tex]-2[/tex] for x
[tex]y=-2+4=2[/tex]
[tex]y=2[/tex]
so range is y values greater than 2
For second function, y value is only -6
So range is [tex](-6)[/tex] U [2,∞)
