Question

Graph the function and find the range

Answer 1

The graph is B because it shows the graph of -4x for when x is less than 0. Also, the closed dot shows that the graph is equal to -4x when x = 0.

The range is [-3]∪(0, infinity)

The "[" is a closed bracket to represent that the lower bound of y-values is equal to -3. On the other hand, the ")" is an open bracket to represent that the upper bound of y-values approaches infinity, but never equals it.
