Answer:
Option (1) No
Explanation:
If a horizontal line passes through a graph from more than one point, function will have more than one x-value for one x-value and the function is not one to one.
From the graph attached,
Horizontal lines (parallel to x-axis) will always pass through two points lying on the graph.
Therefore, the given quadratic function is not one to one.
Option (1) NO is the answer.
