2-137.

Write a single expression using the Trapezoidal Rule that will approximate $A(f(x) = 2x^2 − 4x + 3$, $0 ≤ x ≤ 1$) using $5$ trapezoids of equal height. Do not evaluate the expression.

You know that you’re writing an expression between $0\le x\le 1$ using $5$ trapezoids, so you know that you’ll be starting with $0$ and increasing $x$- values by increments of $\frac{1}{5}$ until you’ve created $5$ trapezoids.
