Answer:
Choice A
Step-by-step explanation:
In order to determine the equation of the graph, we can simply graph the four equations using an online graphing utility like desmos graphing tool and then run a comparison to identify the appropriate equation of the given graph.
Below are the graphs of the 4 given equations. The graphs were obtained using the desmos online graphing utility;
From the graphs below, the graph that matches the given graph is the one obtained from;
y = x cosx
This is the equation of the given graph
