Question 1179669
<br>
Yes; do that....<br>
The instructions are clear; all you need to do is do what it says.  It's not our purpose here to do it for you.<br>
One comment....  Since they ask you to calculate the first and second differences, your table of values needs to have consecutive values for x.  Keep the values small -- maybe from -3 to +3 or something like that.<br>
If you don't understand what they are asking you to do, here is an example using a similar equation.<br>
y = x^2-3x-4<br>
Table of values (using consecutive "small" values of x):<pre>
   x   y=x^2-3x-4
  ----------------
  -2   4+6-4 = 6
  -1   1+3-4 = 0
   0   0+0-4 = -4
   1   1-3-4 = -6
   2   4-6-4 = -6
   3   9-9-4 = -4
   4  16-12-4= 0
   5  25-15-4=6</pre>
First and second differences:<pre>
    6   0  -4  -6  -6  -4   0   6   (the y values for the consecutive x values)
      -6 -4  -2   0  +2  +4  +6   (first differences: differences between successive y values)
        +2 +2  +2  +2  +2  +2   (second differences: differences between successive first differences)</pre>
Presumably one of the things you are supposed to learn from this is that, since the given equation is a polynomial of degree 2, the second differences are constant....<br>
