Consider the following: (a) By reading values from the given graph of $f$, use five roctangles to find a lower estimate for the area under the given graph of $f$ from $x$ a 0 to $x=10$. (Round your answer to one decimal place.) By reading values from the given graph of $f$, use five rectangles to find an upper estimate for the area under the given graph of $f$ from $x$ = 0 to $x$. =. 10. (Round your answer to one decimal place.) (b) Find new estimates using ten rectangles in each case. (Round your answers to one decimal place.) (lower estimate) (upper estimate)
