Answer 1

growth

Answer 2

Eyeball problem. 2/3 < 1 so it is decay.

Answer 3

so growth or decay?

Answer 4

Nope it's decay i agree with @tkhunny

Answer 5

yep I agree, my bad

Answer 6

thanks everyone :)

Answer 7

sorry one more actually...

Answer 8

Without graphing, determine whether the function y = 7(0.28)^x represents exponential growth or exponential decay.

Answer 9

0.28 < 1 -- You tell us.

Answer 10

decay as well?

Answer 11

If the number being raised to x is something between 0&1 then it's decay .. So yeah decay as well
