The function f(x) is a quadratic function continuous over all real numbers. The function f(x) has the following properties:
  • Decreases over the interval (−∞,−38)\Bigg(-\infin,-\dfrac{3}{8}\Bigg)
  • Increases over the interval (−38,∞)\Bigg(-\dfrac{3}{8},\infin\Bigg)
  • Contains zeros at 12\dfrac{1}{2} and 34\dfrac{3}{4}
  • Is congruent to y=3x2y=3x^2
What is the equation of f(x)?
