Mathematics for IGCSE & O level - Graphs Of Functions (Section 5 - No. 14)

In the equation y = a/x, what happens to the graph as x approaches zero (from the positive side)?
y approaches zero.
y approaches infinity.
y oscillates between positive and negative values.
y remains constant.

Explanation

As x approaches 0, y approaches infinity, resulting in a vertical asymptote.
