Extracted text: Consider the function f defined on [0, 1] such that f (0) = f(1) = 1,f(1/5) = f0/5) = 2, and f(2/5) composite Trapezoidal rule with 5 subintervals is 1.8, then the value of cis. %3D f(4/5) = c. Suppose that the approximation of I = f(x)dx by O -0.5 O 0.5 4. Romberg integration for approximating f() dx gives R - I and R 12 then /(0)=
