Given curve: $y = \frac{1}{4} x^2 + 2x + 3$ and associated table of values:
| x | -8 | -6 | -4 | -2 | 0 | 2 |
| y | 3 | 0 | -1 | 0 | 3 | 8 |
Write down one solution of: $\frac{x}{2}+2 = \frac{1}{4} x^2 + 2x + 3$
- Do we rearrange and use the quadratic formula, $x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}$, to find a solution?
- Or can we infer/derive a solution from the table of values?
