Which of the following options results in a graph that shows exponential growth?
f(x) = 0.4(3)x
f(x) = 3(0.5)x
f(x) = 0.8(0.9)x
f(x) = 0.9(5)−x

Question

Which of the following options results in a graph that shows exponential growth? 
 f(x) = 0.4(3)x
 f(x) = 3(0.5)x
 f(x) = 0.8(0.9)x
 f(x) = 0.9(5)−x

I legit have no clue please explain well

mathmale · Answer

Important:  You're discussing exponentiation here.  Please use the symbol " ^ " to indicate exponentiation.  Example:  f(x)=0.4(3)^x    or$$ f(x) = 0.4(3)^x$$

tgstudios · Answer

ok yes they are all exponential

sorry to rush but I'm on a time crunch, its 11:43 where I am

tgstudios · Answer

I am your 600th fan btw @mathmale :D

mathmale · Answer

Thank you very much!   Everything clear to you now, or have you more questions?

tgstudios · Answer

I still need a little bit of explaining, my guess at this problem is 3(0.5)exponent x

tgstudios · Answer

everything else seemed smaller

tgstudios · Answer

I rly need explanation on how to solve it, as I said, my answer is option B

Delete all your pointless posts, you'll be more likely to get help.

If the base (which has the exponent attached) is greater than 1, it's exponential growth.
