Hello!
When you look at the table you see that V(x) is increasing so we know that the answer has the word grow in it.
Next you can substitute one of the x values in one of the equations to see if you get the v(x) value
Next you can do 4(0.65)^1 to see if you get 5.4
When you put it into a calculator you get 2.6
Now you can put 1 in for x for the other equation
4(1.35)^1 to see if you get 5.4
This does give us 5.4
So the answer is C, V(x) = 4(1.35)^x, and it grows.
Hope this helps!
