Estimate the minimum number of subintervals needed to approximate the integral

3 7) Estimate the minimum number of subintervals needed to approximate the integral (a) (3x2 + 6)dx with an abs error less than 1074 using the Trapezoidal Rule. 6 ( b ) 1 4 (x - 1)2 dx with an abs error less than 10-4 using the Trapezoidal Rule. 3 ( c) (6x4 - 7x)dx with an abs error less than 10 4 using Simpson's Rule. 4 (d) Vx +4 dx with an abs error less than 1074 using Simpson's Rule
