what is the domain and range and wether y is a funtion of x? y= - |3x| also what would i put for a list of ordered pairs that satisfy the equation???

Question

please help ive been struggling all day on this homework problem.

Answer 1

Think about transformations of graphs.  The parent function is y=|x|.  This is a vertical stretch of scale factor 3.  The vertex is [0, 0) and the graph opens downward.

 

Domain is all real numbers.  Range is all real number less than or equal to zero.
