Can someone help me to answer all the questions correctly, please, and explain it. Also, would you please in a way I can understand the writing, please.

This is Calculus 1. They came together.

The table gives the values of a function obtained from an experiment. Use them to estimate (x) dx using three equal subintervals with right endpoints, left endpoints, and midpoints. X 3 4 5 6 8 9 f( x) -3.6 -2.2 -0.5 0.2 0.8 1.3 1.8 (a) Estimate "((x) dx using three equal subintervals with right endpoints. R3 = If the function is known to be an increasing function, can you say whether your estimate is less than or greater than the exact value of the integral? O less than O greater than O one cannot say (b) Estimate F(x) dx using three equal subintervals with left endpoints.
