Find the approximate area under the curve of the given equation by dividing the indicated intervals into n subintervals and then add up the areas of me inscribed rectangles. There are two values at and therefore two approximations for the area. The height of each rectangle may be found by evaluating the function for the proper value of x. 1 y=2~. between x=1andx=5for(a)n=4,(b)n=8 x 1 (a) The approximate area under the curve y= 2 for n =4 rectangles is D. x (Round to three decimal places as needed.) 1 (la) The approximate area under the curve y = 2 for n = 8 rectangles IS D. x (Round to four decimal places as needed.)
