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
In primary succession, bare rock or sand is the substrate upon which the pioneer species act. Primary succession occurs in places that are the result of lava flows or where glaciers have retreated. Soil is not yet present, so no plants or animals can survive in such a region.Pioneer species are the lichens and moss.
