Question

Calculus, Riemann sum pic below

Answer 1

largely arithmetic
right hand endpoints means \(f(3),f(7),f(8),f(10)\)

Answer 2

on the interval \([1,3]\) the interval is of length 2 and \(f(3)=0\) from the table, so that give \(0\times 2=0\) for that part

Answer 3

on the interval \([3,7]\) the length is 4 and \(f(7)=3\) again from the table, so that gives
\[3\times 4=12\]

Answer 4

now lets cut to the chase
it is
\[0\times 2+3\times 4+3\times 1+(-4)\times 2\] whatever that is
