Identify whether the data shows exponential GROWTH or exponential DECAY. Then, determine an exponential function to model the situation.

• Exponential Growth; $y=62\left(1.75\right)^x$

• Exponential Growth; $y=62\left(1.34\right)^x$

• Exponential Decay; $y=62\left(1.75\right)^x$

• Exponential Decay; $y=62\left(1.34\right)^x$
