Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96

Answer:
the graph is attached below
Step-by-step explanation:
LEts make a table to get the coordinates
we need to select integers between -3 and 3
x y=x^2 - 2
-2 y=(-2)^2-2=2 (-2,2)
0 y= (0)^2 - 2= -2 (0,-2)
2 y=(2)^2-2 = 2 (2,2)
Now we use the table for graphing the given equation
The graph is attached below
