Name: Joi Williams Date: 3/2/2020 School: Envision Facilitator: 3.07 Vertex Form of Quadratic Functions This task requires you to create a graph. You have several options: Use the Word tools; Draw the graph by hand, then photograph or scan your graph; or Use the GeoGebra linked on the Task page of the lesson to create the graph; then, insert a screenshot of the graph into this task. For each function, identify the vertex, domain, range, and axis of symmetry. Answer yes or no to whether there is a vertical stretch, vertical compression, or reflection over the x-axis. Then, choose the correct graph for each function from the choices below. You will not use all of the graphs. (A) (B) (C) (D) (E) (F)
(G) (H) (I) 1. y = -( x + 4) 2 – 4 Vertex: ( -4 , -4 ) Domain: All real numbers Range: y -4 Axis of Symmetry: x = -4 Vertical stretch: none Vertical compression: none Graph: D Reflection over the x- axis: yes Show work for the second point here: Second Point: ( , ) 2. y = 3( x – 1) 2 Vertex: ( 1 , 0 ) Domain: All real numbers Range: y ≥0 Axis of Symmetry: x = 1 Vertical stretch: yes
