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)?
