The function f is continuous on the closed interval [0,6] and has values that are given in the table below.
x |0|2|4|6 f(x)|4|k|8|12 the trapezoidal approximation for(the integral): 6 s f(x) dx 1 found with 3 subintervals of equal length is 52. what is the value of k?
how do you do this with the formula b-a/(2n) * f(x0) + 2(fx1) + f(xn)?
