- `Optimal value`: y-value for vertex
- `Domain`: List of all valid x-values for relation, expressed as $`D = {num, num2, num3}`$ or as a relation such as $`D = {x E R, x != 0, x < 50`$

- `Domain`: List of all valid **x-values** for relation, expressed as $`D = {x, x_2, x_3}`$ or as a relation such as $`D = \{x \in \mathbb{R}, x =\not 0, x < 50\}`$
