Question: At right is the graph of the quadratic function that passes through (-2.4, 0), (0.8, 0), and (1.2, -2.592). a. Use the x-intercepts to write

At right is the graph of the quadratic function that passes through (-2.4, 0), (0.8, 0), and (1.2, -2.592).
a. Use the x-intercepts to write the quadratic function in factored form. For now, leave the vertical scale factor as a.
b. Substitute the coordinates of (1.2, -2.592) into your function from 8a, and solve for a. Write the complete quadratic function in factored form.
c. The line of symmetry for the graph of this quadratic function passes through the vertex and the point on the x-axis halfway between the two x-intercepts. What is the x-coordinate of the vertex? What is the y-coordinate?
d. Write this quadratic function in vertex form.
