    Not got a calculator here but a cursory look tells me that your value for x = 2.5 cannot be correct based on your other values. Should it be perhaps 0.026?

    Ya your right.

    if im using the trapezoidal rule do I need to draw the graph, do I just plug values in to formula?

    No need to draw the graph to use the trapezoidal rule but the question does ask for it...
