Answer:

Domian x is set of all real numbers (-∞, ∞)

range is
(-6) U [2,∞)

Explanation:

A. Graph the piece-defined function

f(x)={x+4,x≥-2

-6, x<-2

Domain is the set of x values,
x\geq -2, x<-2

Domian x is set of all real numbers

For range we check the y values


y=x+4

Plug in
-2 for x


y=-2+4=2


y=2

so range is y values greater than 2

For second function, y value is only -6

So range is
(-6) U [2,∞)

Answer:

A. see the attached

B. domain: all real numbers; range: [-6, -6] U [2, ∞)

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.
