Step-by-step explanation:
Erase the dot points you already have. We are supposed to substitute those values in the right side of problem 1 into the function as x.
For example if x=-4
[tex] - ( - 4) + 5 = 9[/tex]
If x=-2
[tex] - ( - 2) + 5 = 7[/tex]
If x=0
[tex]0 + 5 = 5[/tex]
[tex] - 2 + 5 = 3[/tex]
[tex] - 4 + 5 = 1[/tex]
So our point should be
-4,9
-2,7
0,5
-2,3
-4,1.
The range is all possible y values in a function. Since this is discrete and we are given the domain, our range will just be the y value of the points you graphed.
(9,7,5,3,1)
