Solution:
1. Choose a set of x-values. Typically, for a quadratic function likef(x) = x^2 - 1 x = -3, -2, -1, 0, 1, 2, 3
2. Calculate the correspondingy x
* Forx = -3
*f(-3) = (-3)^2 - 1 = 9 - 1 = 8
* Forx = -2
*f(-2) = (-2)^2 - 1 = 4 - 1 = 3
* Forx = -1
*f(-1) = (-1)^2 - 1 = 1 - 1 = 0
* Forx = 0
*f(0) = 0^2 - 1 = -1
* Forx = 1
*f(1) = 1^2 - 1 = 0
* Forx = 2
*f(2) = 2^2 - 1 = 4 - 1 = 3
* Forx = 3
*f(3) = 3^2 - 1 = 9 - 1 = 8
3. Create the table:
Columnx
*-3
*-2
*-1
*0
*1
*2
*3
Columnf(x) = x^2 - 1
*8
*3
*0
*-1
*0
