The table gives the values of a function obtained from an experiment. Use the table to estimate 39f(x)dx using three equal subintervals and a right Riemann sum, left Riemann sum, and a midpoint sum.\table[[x,3,4,5,6,7,8,9],[f(x),-3.4,-2.3,-0.5,0.2,0.7,1.3,1.9]](a) Estimate 39f(x)dx using three equal subintervals and right endpoints.R3=If the function is known to be an increasing funtion, can you say whether your estimate is less than or greater than the exact walle of the incegan?less thangreater thanone cannot say(b) Estimate 39f(x)dx using three equal subintervals and left endpoints.
