Express each absolute value function as a piecewise-defined function. SEE EXAMPLE 1

16. f(x) = 6 x]

17. f(x) = -1

18. f(x) = 2x

19. f(x) = -1.50X1

16. f-1 (x) = x/6 found with inverse

17. (0, -1) found this with the x and y intercepts

18. f-1 (x) = x/2 found with inverse

19. f-1 (X) = -0.6X found with inverse also

have a nice day ^^
