Answer 2

to have decay, you'll want the Base of the exponent to be less than 1.
so which of the options has a base that is less than 1?

Answer 3

\[b^x\] where b is the base

Answer 4

its b?

Answer 5

yep ^_^

Answer 6

Yes. If you imagine x is time, then increasing the time will give you a smaller and smaller value for b (whereas for the others it'll make it bigger)

Answer 7

Since its getting smaller you know its decay.
