Explanation:
Concept:
The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
Hence,
From the graph below,
We can see that the graph cuts the x-axis at two points
Therefore,
The zeroes of the graph are
