All of the following statements about finding the definite integral of a piecewise function are true except:
The definite integral of a piecewise function is the sum of the integrals computed over each interval where the function is defined by a single expression.
It is necessary to partition the interval at the points where the function changes its formula in order to accurately compute the area.
The properties of definite integrals allow the evaluation to be broken into separate parts over contiguous subintervals.
To compute the definite integral of a piecewise function over an interval, one can simply evaluate the antiderivative at the outer endpoints without considering where the function’s definition changes.
