Do you know the properties of growth/decay?

anonymous · Answer

No :(

luigi0210 · Answer

It's usually.. 
$$\LARGE y=a(b)^x$$
Where b is between 0 and 1 (decay)
Where b is greater than 1 (growth) 
And $\large a>0$

OKay I remember that now ! Awesome

So by your $\large \color{red}{b}$ value, you can tell it's growth~
