Use four rectangles to find an estimate of each type for the area under the given graph of \( f \) from \( x=1 \) to \( x=9 \). 1. Take the sample points from the left-endpoints. Answer: \( L_{4}= \) 2. Is your estimate \( L_{4} \) an underestimate or overestimate of the true area? 3. Take the sample points from the right-endpoints. Answer: \( R_{4}= \) 4. Is your estimate \( R_{4} \) an underestimate or overestimate of the true area? 5. Use the Trapezoid Rule with \( n=4 \). Answer: \( T_{4}= \) 6. Is your estimate \( T_{4} \) an underestimate or overestimate of the true area?
