le number Learning Target AK: Given an equation, I can graph an absolute value function, f kids. Let . Write ; key features, and determine its inputs and outputs, (4 points each) nario. 14. Graph k(x) = -2|x| + 3 15. Graph r(x) = = |x - 21 it is the s Use the absolute value function, f (x), to answer questions 16 - 21. (#16 4pts, #17 - 21 2pts each) If a re f(x) =-51x+41+6 16. Graph the function f (x) 17. Evaluate f (1) = e var 18. Evaluate f (-20) = 19. For what value(s) of x does f (x) = 10 -9 8 -7 0? 10 20. For what value(s) of x is f (x)
