Question 198525
<font face="Garamond" size="+2">


Since this is supposed to be an exponential function, I am presuming that you meant:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ H = pa^t]


To avoid confusion, use ^ to indicate raising to a power in the future.  As in:  H = p*a^t


The following are graphs of


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 25(0.9)^t,\ t \geq 0] (the red graph)


and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 25(1.1)^t,\ t \geq 0] (the green graph)


Draw your own conclusions:


{{{drawing(
500, 500, 0, 100, -10, 100,
grid(1),
graph(
500, 500, 0, 100, -10, 100,
25*(0.9)^x,
25*(1.1)^x
))}}}
