Answer:
D . . . (it represents a quadratic function)
Step-by-step explanation:
The x-values are 1 unit apart for all values in all tables, making the problem much simpler. All you need to do is find the table where the y-value differences are not the same from one line to the next.
In table A, y-values decrease by 3.
In table B, y-values increase by 5.
In table C, y-values increase by 1.
In table D, y-values increase by 3, 2, 1—numbers that are not constant. (These differences decrease by 1, a number that *is* constant. Since the 2nd differences are constant, the table represents a 2nd degree function.)
1.5 is less then or equal to x which is less then or equal to 14.5
Answer:
n = -7
Check:
-4 - 3 + 5 + 4 - 3 + (-7 ÷ -7) = 0
-1 - 7 ÷ -7 = 0
-1 + 1 = 0
0 = 0
Slope-intercept form: y = mx + c
10x - 5y = -17
move 10x to the other side.
- 5y = -10x - 17
