23. Sketch the graph of each function. List and label the coordinates of any extrema and points of inflection and state where it is concave up or down. a) f(x) = -2x^3 + 12x^2 - 18x + 6 b) f(x) = 8x - x^2 - 8 24. a) This is a graph of f(x). b) List the intervals where f(x) is increasing and where it is decreasing. c) State the x-values where the graph of f(x) has relative maxima and relative minima. d) Determine the relative extrema on the graph of f(x). e) List the intervals where the graph of f(x) is concave up and where it is concave down. f) List the x-values where the graph of f(x) has an inflection point. 25. f(x) = 3x + 6x - 5 26. f(x) = 27.

Chapter 34, Problem 046 Your answer is partially correct. Try again. An object is placed against the center of a thin lens and then moved 110 cm from it along the central axis as the image distance $i$ is measured. The figure gives $i$ versus object distance $p$ out to $p_1 = 50$ cm. What is the image distance when $p = 110$ cm?
