the approximate value of the area between the graph of the f(x)=3x^2+2 and the intergral [0,1] by choosing n=5 rectangales is given by :
a) 18 over 5 sq units
b) 68 over 5 sq units
c) 68 over 25 sq units
d) 25 over 68 sq units
I think you mean the area between f(x) and the x-axis over the interval from x= 0 to 1.
Note: This is not a very good approximation to the true value of 3.
thank you so much
