Which is the graph of a quadratic equation that has a positive discriminant?

  f(x) = 3x^2  + 7x  + 2.  for this case, the discriminant will be given by  b ^ 2 - 4 * a * c  where  b = 7  a = 3  c = 2  substituting  b ^ 2 - 4 * a * c = (7) ^ 2 - 4 * (3) * (2) = 25  therefore the value of the discriminant is 25.  attached the graph

Answer is either b or c
