Answer:
C
Explanation:
The discriminant informs us about the nature of the zeros
• If b² - 4ac > 0 then 2 real and distinct zeros
• If b² - 4ac = 0 the 2 real and equal zeros
• If b² - 4ac < 0 then zeros are not real
The graph crosses the x- axis at 2 distinct zeros, then
b² - 4ac > 0 , that is positive → C
