Question

.

Answer 1

the base is 0.2

is that less than 1? or greater than 1?

Answer 2

less than one

Answer 3

so that means that as x increases, y will decrease

therefore, we have exponential decay

Answer 4

in general

y = a*b^x

if b > 1, then we have exponential growth
if b < 1, then we have exponential decay

Note: b > 0 to avoid getting imaginary/complex answers

Thank you so much ! ! (:
