Split up the interval [0, 3] into 3 equally spaced subintervals of length 
. So we have the partition
[0, 1] U [1, 2] U [2, 3]
The left endpoint of the 
-th subinterval is
where 
.
Then the area is given by the definite integral and approximated by the left-hand Riemann sum
10/22 in simplest form is 5/11
They are mad as easy try it on your own your answer is suppose to be 80
2(x+5) =20 is the translation
Because g(x) passes from 1,0 to 1,4, we can say that it has a slope of 0. f(x) has a slope of 2.
