Riemann Sum

[nikchic5]

Please help me as soon as you can! I am really confused and I have a tes tomorrow!
Evaluate the Riemann sum for f(x)= 5 - (x^2), 0 is less than or equal to x is less than or equal to 2 , with four subintervals, taking the sample points to be right endpoints.




THANK YOU SO SO SO MUCH FOR YOUR HELP!!!!

\(\displaystyle R = \Delta x [f(x_1) + f(x_2) + ... + f(x_n)]\)

where \(\displaystyle \Delta x = \frac{b-a}{n}\)
