Question

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

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

Answer 1

Multiply by three

Explanation:

At 0 seconds, mph is 4

1 second, multiply by three.

second 2, still multiply by 3.

And so on.

Answer 2

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

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.
