Question 183557
The general form of any exponential equation is {{{y=a*b^x}}}. If {{{b>1}}}, then as "x" increases, then "y" increases at an exponential rate. If {{{b<1}}}, then as "x" increases, then "y" decreases at an exponential rate (ie it exponentially decays).


So in the first equation {{{b=7>1}}}, this tells us that the first equation represents exponential growth.



On the other hand, in the second equation, because {{{b=0.5<1}}}, this means that the second equation represents exponential decay.
