Question

The axis of symmetry of a parabola is x=4.6. It crosses the x -axis at (0.6,0). What is the x -coordinate of the other point where the parabola crosses the x -axis?

Answer 1

keeping in mind that the vertex of a parabola is halfway between the x-intercepts, if a point is a 0.6, and the vertex is at 4.6, that's just 4 units over to the right, thus the other point will have to be 4 units further, check the picture below.
