4.2: You have a function f, which is calculated according to: f(x) = 2-x + 2| - |x – 11. a. Type f (x) as an individually defined function, without the punctuation mark. b. Draw the curve y = f (x) in a graded coordinate system. c. Solve the equation 2:x + 2| - x - 1| = 4 using case division. d. Confirm that the calculated solutions are correct by inserting them in the original formula for f (x). If you also got some fake roots, check them out as well. e. Draw the line y = 4 in the coordinate system in problem (b). f. Explain how you see the solutions to the equation in problem (c) in the picture. 4.2: You have a function f, which is calculated according to: f(x) = 2-x + 2| - |x – 11. a.
