Suppose that the only information we have about a function is that f (1) = 5 and the graph of its derivative is as shown.
(a) use a linear approximation to estimate f (0.9) and f (1.1).
(b) are your estimates in part (a) too large or too small? explain.

The weight of a radioactive isotope was 96 grams at the start of an experiment. after one hour, the weight of the isotope was half of its initial weight. after two hours, the weight of the isotope was half of its weight the previous hour. if this pattern continues, which of the following graphs represents the weight of the radioactive isotope over time? a. graph w b. graph x c. graph y d. graph z
