Graphing y = (x - h)2 + k. In the graph of y = x 2 , the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex. Observe the graph of y = x 2 + 3 : Graph of y = x 2 + 3.
The Euglena Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis.aramecium Paramecium are unicellular protozoans classified in the phylum Ciliophora (pronounced sill-ee-uh-fore-uh), and the kingdom Protista.
