Question

what type of symbolic representation is shown below?
$delta t = t_f - t_i$
graphical relationship
mathematic relationship
chemical symbols

Explanation:

The given expression $\Delta T = T_f - T_i$ is a mathematical equation. A graphical relationship would involve a graph (like a line graph, bar graph etc.). Chemical symbols are used in chemistry to represent elements (e.g., H for hydrogen, O for oxygen). Since the given $\Delta T = T_f - T_i$ is an equation (a form of mathematical representation), it is a mathematic relationship.

Answer:

Mathematic Relationship
