Question

determine if this equation represents exponential growth or decay

Answer 1

\[y = (0.9)^{x}\]

Answer 2

just take few value of x , you can see whether it is up or down. for example:
x =1 --> y = 0.9
x =2 --> y = (0.9)^2 = 0.81
x =3 --> y = (0.9)^3 = 0.729
you see!! x increases, y decreases--> so the function is.... ????

Answer 3

decay?

Answer 4

Yup

Answer 5

thank you! would you be willing to stick around and help me with others

Answer 6

In general, to exponential equation, the base >1 --> function grow
the base <1 --> function decay.
your base 0.9<1 --> decay

Answer 7

The parent function of the following graph is
\[f(x) = (\frac{ 1 }{ 2 })^{x}\]
