14. An engineer recorded the acceleration of an experimental rocket.

 time (sec) 0 1 2 3 4 speed (mph) 4 12 36 108 324

if looking for the function that best models graph, f (x) = 4 * (3^x) is the function that satisfies values.

Step-by-step explanation:

f (0) = 4 * (1) = 4

f (1) = 4 * (3) = 12

f (2) = 4 * (9) = 36

f (3) = 4 * (27) = 108

f (4) = 4 * (81) = 324

These are the same x and y values.

Multiply by three

Step-by-step explanation:

At 0 seconds, mph is 4

1 second, multiply by three.

second 2, still multiply by 3.

And so on.
