Question

By seeing the following graph, determine whether the discriminant is greater or equal or less than zero.

  1. Greater    
  2. Lesser    
  3. Equals    
  4. Cannot be determined    

Hint:

For a quadratic equation, if discriminant is greater than zero then it has two unequal real roots. If discriminant is equal to zero then it has two equal real roots and is the discriminant is less than zero then it has no real root.

The correct answer is: Greater


    Step by step solution:
    The graph intersects the x - axis at two places, so the graph has 2 unequal real roots.
    Thus, the discriminant is greater than zero.
    hence, option(b) is the correct option.
