Identify the vertex and y intercept of g(x) = -3(x+2)² + 5. remember the parent function is f(x) = x² and graph the parent function and g(x) =-3(x+2)² + 5. (2,-5) vertex ; y intercept is (0,-5) (-2,-5) is vertex ; y-intercept is (0,-5) (2,5 is vertex ; y-intercept (0,5) (-2,5) is vertex ; y-intercept (0,5)

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
