Please answer with an explanation ​

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.

What is the graph of the function fx x+2/x-3?
