Jen conducts a pendulum experiment using the tire swing in her backyard. She raises the tire to a height of 1.8 meters above the ground and allows it to swing back and forth. The tire's maximum height above ground decreases by about 28% on each swing. You can use a function to approximate the height of the tire above the ground when it has completed x swings.
Write an equation for the function. If it is linear, write it in the form g(x)=mx+b. If it is exponential, write it in the form g(x)=a(b)x.
g(x)=
