Answer:
D. T-chart using random values for x and y
Step-by-step explanation:
We are given that,
To graph an exponential function, we take few points and then connect them.
So, while using a T-chart, we need to know the type of points to take.
As, in order to plot the graph, we are using few points and then connect them.
This gives that, we will take few random values of x and y to complete the T-chart and plot the graph.
Hence, option D is correct.
