The length of a snake in a video game doubles every minute. The function f(x) = 10 • (2)x represents the length of the snake in centimeters (cm). The time x = 0 represents when the game started.
A. Label the correct axes with "Length (cm)" and "Time (minutes)."

B. Graph f(x) = 10 • (2)x.

C. On the graph, plot and label the y-intercept.

D. Which values of x make sense in terms of this problem? Explain your reasoning. Make sure your graph shows these values.
