Verify that the symmetric difference quotient produces the exact derivative value for a quadratic function f(x) = ax2 +bx+c. (Hint: Show that
f(x +h)-f(x-h)/2h
= 2ax + b
provided h≠0)

If you answer 2+2 you will get over 80 points

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part 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 (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
