Question

y=(2/3)^x growth or decay

Answer 1

Whatever the number is being raised to the x, let's call it C, it's a costant, and in this case it's 2/3, theres a simple rule that governs this.
If C < 1 then it is decay,
If C > 1 it is growth!

Answer 2

actually,
if 0<C<1, it's decay...

Answer 3

Omg I don't get it. I understand growing is increasing and decay is decreasing but the problems its showing me as examples arent like that!

Answer 4

yes... you're right.... that's what a decay/growth should look like on a graph....
but analytically, what @Eleven17 gave you are the conditions on the expression to determine whether an expression is growth or decay (without the graph).

Answer 5

Okay in get it now lol. Thanks ! Just one more thing . ..
