Using the graph of the function f(x) = x-x+1 i. Find approximate x values for any local maximum or local minimum points. ii. Set up a table showing intervals of increase or decrease and the slope of the tangent on those intervals. iii. Set up a table of values showing "x" and its corresponding "slope of tangent" for at least 7 points iv. Sketch the graph of the derivative using the table of values from (iii) above Repeat question using the function f(x) = (x-3)(x - 1)(1-x)
