Which of the following statements are true?

  1. If, f(x) = 2x2 − 5 and g(x) = 2x2 + 4, then the graph of f(x) is 9 units above the graph of g(x).
  2. Sum of the zeros of the function f(x) = (2x − 3)(x − 4) is 4.5.
  3. The y-intercept of the function whose graph has a slope of −3 and passes through the point (6, 4) is 14.
  4. If the domain of the function f(x) = 12x2 + 2 is {−4, 0, 3}, then the range of the function is {194, 2, 110}.
  5. If f(x) = 6x2 and g(x) = x2/6, then the graph of f(x) will be narrower parabola as compared to the graph of g(x).
  6. If a graph shows the relationship between the amount of sand in the top of an hourglass y, over time x, then the x-intercept of the graph represent the speed at which the sand passes to the bottom of the hourglass.
