2. Graph the function f(x) = x2+1 and its derivative in the window [-3,3] by [-1, 1]. Now answer the same set of questions as in #1 above: a. Over what intervals does the graph off appear to be rising as x moves from left to right? (for a f(b)) d. Over what intervals does the graph off' appear to be below the x-axis? e. What are the x-coordinates of all of the peaks and valleys of the graph off? f. For what values of x does the graph of f' appear to meet the x-axis? 3. On the basis of your looking at the graphs of a function and its derivative in #1 and #2, write a statement (or statements) about properties you have observed about the graph of its derivative. a. What do you observe about the graph of the derivative when a function is rising? b. What do you observe about the graph of the derivative when a function is falling? c. What do you observe about the graph of the derivative when a function has a peak or a valley
