Final answer:
d) Double-sided arrow line
The symbol \(\Rightarrow\) represents a double-sided arrow line used in mathematics to indicate a relation or implication going in both directions.
Step-by-step explanation:
The symbol \(\Rightarrow\) represents d) Double-sided arrow line.
In mathematics, the double-sided arrow line, \(\Rightarrow\), commonly known as a double-headed arrow or a bi-directional arrow, is used to indicate a relation or implication going in both directions. It implies that the statement or equation before the arrow is equivalent to the statement or equation after the arrow.
For example, if we have the equation \(2x + 1 = 5\) \(\Rightarrow\) \(x = 2\), it means that solving the equation \(2x + 1 = 5\) leads to the result \(x = 2\).
