5. True / False a. A quadratic function is a polynomial function raised to the second degree. b. The graph of a quadratic function is the circle. If the quadratic function is in vertex form, then the values that in the place of h and k is the vertex of parabola. d. If the leading coefficient to the quadratic equation is positive then the parabola will open downward. e. If the parabola opens upward, then the vertex is the maximum point. f. The domain of the quadratic function is always all real numbers. B . If the quadratic function is in standard form, then the constant value is the constant value is the y-intercept. Convert the vertex form of the following quadratic to standard form. f(x) = -3(x - 1)2 - 4 7. Determine the following characteristics from the graph of the quadratic function.
