Question

anonymous · Answer

I'm not sure but what kind of assinment is this

anonymous · Answer

@chickennamednuggets in my class it says exponentials

anonymous · Answer

Okay is this homework, test, or just a classroom worksheet

anonymous · Answer

@chickennamednuggets it is homework

anonymous · Answer

if the base is bigger than one growth
if the base is less than one, decay
y=Abx
 b is the base

anonymous · Answer

I learned that, but it doesn't quite make sense to me.. Some of them done have 2 numbers, like the one above.

anonymous · Answer

don't*

anonymous · Answer

$$4^x$$ grows real real fast 
it is growth, not decay, because $4>1$

anonymous · Answer

look at the number so its 4 and we said if the number is less than one then its decay and if its bigger than one it will be growth

anonymous · Answer

Oh, ok. That makes more sense.

anonymous · Answer

so u get it now ?

anonymous · Answer

Sort of.

anonymous · Answer

So would y = 2.1(0.15)x be a growth?

anonymous · Answer

what are u still confused on

anonymous · Answer

is $0.15$ bigger than one or less?

anonymous · Answer

Less

anonymous · Answer

well do distributive property first so whats 2.1 times 0.15

anonymous · Answer

So it would be a decay. Ok, I think I finally understand.

anonymous · Answer
