The function f(x)=|x| is given with g(x)=|kx| . Since f(a)=|a|, what is g(a)? Justify your response. g(a)=k+f(a) since the graph of g(x)=|kx| has a height that is k
k
units greater than the height of f(x) for any given x

.

g(a)=f(a)−k since the graph of g(x)=|kx| has a height that is k
k
units less than the height of f(x) for any given x
