- A1 (a repeated/coincident zero)
- B0
- C2 distinct
- D3
Step-by-Step Solution
When the parabola touches the -axis at a single point, the two zeroes coincide, so there is one (repeated) real zero.
Answer: A) 1 (a repeated/coincident zero)
If a quadratic polynomial's graph just touches the -axis at one point (does not cross it), the number of real zeroes is:
