The function k is defined bya. Sketch the graph of y = k(x).
b. Explain why it is not necessary to sketch y = |k(x)| and y = k(|x|).

The function m is defined by

c. Sketch the graph of y = m(x).

d. State with a reason whether the following statements are true or false.

i. |k(x)| = |m(x)|

ii. k(|x|) = m(|x|)

iii. m(x) = m(|x|)

a k(x) = -2, a > 0, x R, x 0.
