Answer:-11
Step-by-step explanation:
Plugging in -3 to the graph, we get that the K(-3) value would be equal to 2. We can plug that into the first part of the equation, getting us:
5(2)-7K(-4).
If we plug in -4 to the graph, we get that the K(-4) value would be equal to 3. We can plug this into the second part of the equation, getting us:
5(2)-7(3). Simplified, this would be
10-21, or -11
