Question

Type your response in the box. How can you tell whether an exponential equation models growth or decay? Use the general form of an exponential expression to explain your answer.

Answer 1

growth means increment of graph

eg.,
$ae {}^{x}$
this is increasing graph.... (as x increases value of function also increases)


on the other hand

$ae {}^{ - x}$
as x will increase this function will decrease, so it's a decay function...
