Solution
This statement is False.
Explanation:
If the graph of a polynomial intersects the x-axis at only one point
Then it cannot be a quadratic polynomial because a quadratic polynomial may touch the x-axis at exactly one point or intersects x-axis at exactly two points or do not touch the x-axis.
