Question

how can we tell that this is function or equation?​

Answer 1

Answer:

You can tell whether a relation is a function by plotting the numbers on a graph and applying the vertical line test. If no vertical line passing through the graph intersects it at more than one point, the relation is a function.

Answer 2

Answer:

A function is a set of ordered pairs where each input (x-value) relates to only one output (y-value). ... Equations are functions if they meet the definition of a function. But, there are equations that are not functions. For example, the equation of a circle is not a function.
