Find the values of the expression for x = -2, -1, 0, 1, 2 This question is asking us to evaluate the expression for five different values. It may be easiest to do this in chart form. X | 3x^{2} + 1 | Simplified | -2 | 3(-2)^{2} + 1 | 3(-2)^{2} + 1 3(4) + 1 12 + 1 13 | -1 | 3(-1)^{2} + 1 | 3(-1)^{2} + 1 3(1) + 1 3 + 1 4 | | 3(0)^{2} + 1 | 3(0)^{2} + 1 3(0) + 1 0 + 1 1 | 1 | 3(1)^{2} + 1 | 3(1)^{2} + 1 3(1) + 1 3 + 1 4 | 2 | 3(2)^{2} + 1 | 3(2)^{2} +1 3(4) +1 12 + 1 13 |

The answers can be expressed as ordered pairs, with the x value first and the answer second. Here are the answers in this form: (-2, 13), (-1, 4), (0, 1), (1, 4), and (2, 13) | |
