Answer: see below
Step-by-step explanation:
#5 - 7: Domain are the x-values and Range are the y-values.
5) Coordinates are: (-2, 3), (0, 3), (2, 3), (4, 3)
Domain: x = {3} Range: y = {-2, 0, 2, 4}
6) All points on the curve between -4 and 2 (x-values) & 3 and 6 (y-values). Endpoints are included.
Domain: -4 ≤ x ≤ 2 Range: 3 ≤ y ≤ 6
7) All points on the curve between 2 and 7 (x-values) & 1 and 6 (y-values). Endpoints are not included.
Domain: 2 < x < 7 Range: 1 < y < 6
#8 - 11: Choose points for x. Plug them into the equation to solve for y.
To graph the equation, plot the points and connect the dots.
8) x y = x
-2 -2
-1 -1
0 0
1 1
2 2
9) x y = 2x+1
-2 2(-2)+1 = -3
-1 2(-1)+1 = -1
0 2(-0)+1 = 1
1 2(1)+1 = 3
2 2(2)+1 = 5
