How about if someone shows you how to do one and you do the rest? The average of f'(x) over an interval a to b is the area under the f'(x) curve, divided by (b - a). That equals f(b) - f(a), because the area under f'(x) dx is the integral, f(x) A. f(-2) - f(-3) = -8 +16 +9 -(-...

I assume you mean make the area under the curve 1.0 in the interval. Area=Constant*INT e^-5x dx from 0 to infinity 1.0=constant* (-1/6 e^-6x ) over the limits 1.0= constant*1/6(e^0 -e^-inf) 6= constant. check my work, My mind today is wavering, allergy meds today.
