This is what the graph looks like: The parabola only just touches the x-axis at x = â2/3; it doesn't actually cross. This is always true: if you have a root that appears exactly twice, then the graph will kiss the axis there, but not pass through.1  Solve 3x2 + 4x + 2 = 0.hen the answer is: x = â1.24, x = 3.24, rounded to two places. For reference, here's what the graph looks like: There is a connection between the solutions from the Quadratic Formula and the graph of the parabola: you can tell how many x-intercepts you're going to have from the value inside the square root.
The definition of a plummet is something that weighs something else down. An example of plummet is a weight tied to a piece of material. Plummet is defined as to fall down quickly and suddenly. An example of plummet is for a model airplane to quickly plunge from the sky.
vertical, perpendicular, plumb mean being at right angles to a base line. vertical suggests a line or direction rising straight upward toward a zenith. â¨the side of the cliff is almost verticalâ© perpendicular may stress the straightness of a line making a right angle with any other line, not necessarily a horizontal one. the parallel bars are perpendicular to the support posts; plumb stresses an exact verticality determined (as with a plumb line) by earth's gravity. make sure that the wall is plumb
