The base of the function $y={1.8}^{x}is1.8>1,$
so the function represents exponential growth.
Look at the base to determine whether it is growth or decay. If the base is greater than 1, the function represents exponential growth. If the base is less than 1, the function represents exponential decay.
To sketch the graph, find a few points (x,y) by choosing some value x and calculating its pair
$y={1.8}^{x}$, then drawa smooth curve through those points.
