On the interval (−∞,−3), the condition for the function q(x) is -6/5x.
This is a linear function that has a negative slope.
Out of the six graphs, graphs 2 and 4 are linear.
Graph 2 is a linear function with a positive slope.
Graph 4 is a linear function with a negative slope.
Therefore, the general shape and the direction of the graph of function q(x) on the interval (−∞,−3) is represented by Graph 4.
