Question:

Your computer algebra system (CAS) may allow the use of parameters in defining functions. In each case, draw the graph of y = f(x) for the specified values of the parameter k, using the same axes and - 5 ≤ x ≤ 5.
(a) f(x) = |k, x|0.7 for k = 1, 2, 0.5, and 0.2.
(b) f(x) = |x - k|0.7 for k = 0, 2, - 0.5, and - 3.
(c) f(x) = |x|k for k = 0.4, 0.7, 1, and 1.7.
