Given f (x) = V3 + x + 4. Use the definition of 4.4.3 to evaluate each of the area in the range [0, 6] if n = 4. a) Find the area under the curve when xx is the left endpoint of the subinterval. b) Find the area under the curve when xx is the midpoints of the subinterval. c) Find the area under the curve when xx is the right endpoint of the subinterval. 4.4.3 DEFINITION (Area Under a Curve) If the function f is continuous on [a, b] and if f(x) 2 0 for all x in [a, b], then the area A under the curve y = f(x) over the interval [a, b] is defined by n A = lim (2) 1->too * = 1
