Find the domain and range of the graph
ozzi

9514 1404 393

Answer:

  • domain: [-6, -1)
  • range: [-5, 4]

Step-by-step explanation:

You have correctly determined the domain to be from x = -6 to x < -1. In interval notation, that would be ...

  [-6, -1)

__

The range is the vertical extent of the graph. It extends from a minimum of y = -5 to a maximum of y = +4 at the top of the curve. In interval notation, that would be ...

  [-5, 4]

The length of a picture frame is 2 inches more than the width. The perimeter of the frame is 36 inches. What is the length of th
ollegr [7]
Answer in one complete sentence:
____________________________________________
   "The length of the frame is ten (10) inches."
_____________________________________________
Explanation:
_____________________________________________
Perimeter = P = 36 in.
Length = L = 2 +2
Width = w .
_____________________________________________
These are the two equations for the system of equations:

P = 2L + 2w = 36 in.
L = 2 + w
_____________________________________________
Solve for "L" (length) of the frame.
______________________________________
In the equation:
______________________________________
P = 2L + 2w = 36.

{Note: standard knowledge; and/or look up: 
______________________________________
Formula for the Perimeter of a rectangle:  P = 2L + 2w} ;
_______________________________________
We are given:  P = 36 in.
 
Rewrite, substituting "2+w" for "L" ;

P = 2(2+w) + 2w = 36 ;
___________________________
Note:  2(2+w) = 2*2 + 2w = 4 + 2w .

Now, Rewrite the equation, substituting "(4 + 2w) for "2(2+w)" ;
__________________________________________________
P = (4 + 2w)  + 2w = 36 ;

P =  4 + 2w + 2w = 36 ;

Combine the "like terms" ;
____________________________________________
  + 2w + 2w = 4w ;
____________________________________________
   P = 4 + 4w = 36 ;  
____________________________________________
↔   4 + 4w = 36 ;
____________________________________________
Subtract "4" from EACH SIDE of the equation:
____________________________________________
  →  4 + 4w − 4 = 36 − 4 ;
____________________________________________
 to get:
____________________________________________
            →  4w  =  32 ;
____________________________________________
            → Divide EACH SIDE of the equation by "4" ; to isolate "w" on one side of the equation; and to solve for "w" ;  
____________________________________________
            →  4w / 4 = 32 / 4 ;

               →  w = 8 .
____________________________________________
Now, to solve for: "L" (the length).
____________________________________________
    Length:  L = 2 + w ; 

                 →  L = 2 + 8 = 10 inches.
____________________________________________
Answer in one complete sentence:
____________________________________________
   "The length of the frame is ten (10) inches."
