Pablo generates the function f(x) = 3/2 (5/2)^x-1 to determine the xth number in a sequence

1. f(x+1) = 5/2 f(x)

2. f(x) = 5/2 f(x+1)

3. f(x+1)=3/2 f(x)

4 f(x) = 3/2 f(x+1)

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)
