    help with riemann sum

    use a right-hand sum with 4 equal subintervals to approximate the integral \int_{-1}^{3}\left|2x-3 \right|dx


    mysteps
    - \Delta x=\frac{4}{4}=1
    - c1=????
    - I know that i need to get the endpoints for the interval. But i forget how.

    All help is appreciated..

    f(x) = |2x-3|

    \Delta x = \frac{b-a}{n} = \frac{3 - (-1)}{4} = 1

    right sum ...

    \int_{-1}^3 f(x) \, dx \approx f(0) + f(1) + f(2) + f(3)
