State and explain whether the function f(x) = 1.5^-x represents exponential growth or decay.
Any help is appreciated! Thanks.
I did...has negative behavior, which I would think makes decay...
...However, I don't understand, does the negative in the exponent turn it into a fraction -- 1/(1.5^x) ?? And also, negative decay is less than one, and 1.5 is bigger than one...can you help clear this up for me?
Thanks for your help!
