a) Identify the following key features from the graph. Feature Vertex Description (-1,-9) -4,2 S X y -6 3 -4 -3 65732701 x-Intercept(s) y-intercept -2 3 -8 -1 8 Domain Range (-88) (-9,0) IG 24 LEVEL 3 I can identify the vertex, x-intercepts, y-intercept, line of symmetry, intervals of increasing and decreasing, maximum/minimum, domain, and range of a quadratic function. a) Graph the function y = -x-2x+3, complete the table of values, and identify the key features. I can graph given an equation. I can sketch a graph given a description. I can use interval notation correctly.
