Then 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.hen the answer is: x = â1.24, x = 3.24, rounded to two places.

Primary Plant Succession The process of plant succession begins just as soon as a land area capable of supporting plant life is formed. Some examples: accumulation of sand dunes at the edge of the ocean or a lake cooling of a lava flow exposure of rock by a retreating glacier Bare rock succession in a temperate deciduous forest biome
Primary succession occurs on ground which had no previous  vegetation, including lava flows, bare rock and sand dunes. For  example, newly created volcanic island    â¦ Secondary Succession follows the destruction or modification  of existing vegetation, either naturally or by human activity. Primary Succession occurs on surfaces where no soil exists, And  Secondary Succession follows a disturbance that destroys a  community without destroying the soil.   Primary succession is slow and secondary succession is rapid.
