Really confused on this. More interested in the actual steps than just an answer. Thank you so much!

The table below gives selected values for the function f(x). Use a trapezoidal estimation, with 6 trapezoids to approximate the value ofint [1, 2] f(x)dx. Give 3 decimal places for your answer.

x 1 1.1 1.2 1.5 1.7 1.9 2.0

f(x) 1 2 4 6 7 9 10
