Question

without graphing, determine whether the function represents exponential growth or exponential decay then find the y-intercept y=129(1.63)^x

Answer 1

growth

Answer 2

I am not with you@***[ISURU]***

Answer 3

it's growth just because the base of exponential is>1, I mean (1.63) >1 , the function is growth.
If it is <1, then the function is decay.
let do some calculation
(1.63)^0 = 1
(1.63)^1 = 1.63
(1.63)^2 = 2.6569
as x up, the value of function up--> growth
If the base is <1 , let say 0.2
(0.2)^0 = 1
(0.2)^1 = 0.2
(0.2)^2 = 0.04 and so on
as x up, the value of function down--> decay

Answer 4

what is the problem is as follows:
f(x) = 2^-x ?
would it just be a straight line? see, i'm horrible with math, so i'm probably wrong..i'm just curious.

Answer 5

srry for my mistake :( .. u r correct... thanks for clearing it out :)

Answer 6

everybody has mistake, me too. :)
