(1 point) c) what is the maximum/minimum value if any (1 point) d) can you determine the equation (2 points) 2. Solve the following graphically: a) 3x=7 (1 point) b) 11x+1=17 (1 point) c) at what point does the function y = (3x+2)(x-5) reach its maximum/minimum value (1 point) 3. Edgar receiver $500 for this birthday. He wants to invest that money. He has 2 investment options: Option A: A treasury bond that offers 8% simple interest. It is represented by the equation: A=500 (1+0.08n) where n represents time in years Option B: A savings account that offers 6.5% interest compounded annually.
