To understand the behavior of the function
over the interval from
to
, we can calculate the values at these points. At
,
. At
,
. Therefore,
increases from 1 to 3, which is an increase of
or specifically an increase by a factor of 3, but none of your options accurately describe this increase, since the closest would be saying it grows significantly rather than any decreases.
To avoid common pitfalls when evaluating exponential functions, remember that they always increase for positive bases greater than one. A common mistake is to assume they decrease within a certain interval, but instead, they consistently rise as the input grows in this context. Always check your values for boundary points to see the true behavior!
