Answer
Brief Explanations:
When a function is concave up, the trapezoids used in the trapezoidal - sum lie below the curve of the function, resulting in an underestimate of the actual area under the curve. When a function is concave down, trapezoids over - estimate. Whether a function is increasing or decreasing does not directly determine if the trapezoidal sum is an underestimate or overestimate.
Answer:
concave up
