Chapter 1.2, Problem 29SBE

For these exercises, round all estimates to one decimal place.

Another Table The following is a partial table of values for $f=f\left(x\right)$.

$x$	$f=f\left(x\right)$
0	$5.7$
5	$4.3$
10	$1.1$
15	$3.6$
20	$-7.9$

Use this table to complete Exercises S-21 through S-30.

Average Rate of Change Calculate the average rate of change from $x=15$ to $x=20$. Use your answer to estimate the value of $f\left(19\right)$.
