Which is true about the error when approximating the integral of the linear function f(x) = 3x for an interval of [0,1]?

• The error in Trapezoidal rule is half of that in Simpson's rule
• The error is larger using Simpson's 1/3 rule compared to Trapezoidal rule
• The error is smaller using Simpson's 1/3 rule compared to Trapezoidal rule
• The error is equal to zero using Simpson's 1/3 rule compared to Trapezoidal rule Correct
