Answer:
the marked choices are correct
Explanation:
The coefficient of the exponential factor is the value of the y-intercept of the graph.
Graphs B and C, respectively, have y-intercepts of 1/4 and -1/4, so correspond to functions r(x) and s(x), respectively—as shown in the picture.
Graphs A and D presumably have y-intercepts of 4 and -4, respectively, so will correspond to functions p(x) and q(x)—as shown in the picture.
The choices marked in the picture are correct.
