Answer:

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

The expression represents an exponential growth function.

Step-by-step explanation:

Given that $y=5(14)^{\frac{t}{6}$

To rewrite the given equation in the form $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

$y=5(14)^{\frac{t}{6}$

$=5((14)^{\frac{1}{6}})^t$

$=5[1.5525]^t$

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

Since 1.5525 > 1, we have that the expression represents an exponential growth function.
