IV. True or False. Read and answer the following items. Write T if the statement is true and F if the
statement is false. Write your answer before each number.
True 1. The parabola of a quadratic function opens upward if a > 0 and the vertex is the minimum point of
the function.
True 2. The parabola opens downward if a < 0 and the vertex is the maximum point of the function.
True_3. The point of intersection of the parabola and the y-axis is the x-intercept of the graph of the
quadratic function.
4. The point of intersection of the parabola and the x-axis is the y-intercept of the graph of the
quadratic function.
5. The zeros of a quadratic function are equal to the values of x where the function value is equal to 0.
6. The graph of the quadratic function y = 2x2 passes through the point (2,4).
7. The quadratic function y=-(x + 2)2 has only one distinct x-intercept.
8. The coefficient of the x2-term in a quadratic equation is negative, then the vertex of the parabola is
the maximum point.
9. When deriving the equation of the quadratic function given its graph, the vertex and any point on the
parabola can be used except the y-intercept.
10. The point (-1,16) is on the graph of the quadratic function y = x2 - 7x +8.​
