Graph the function f(x) = 16(1.87)x. Does this function show growth or decay? What is the equation of the asymptote?

Growth; y = −16
Growth; y = 0
Decay; y = −16
Decay; y = 0
The function f(x) = 16(1.87)x shows growth. The equation of the asymptote is y = 0.
The same amount of trash is dumped into a landfill every day. The function below shows the total number of tons of trash n in the landfill after x days:

Which of the following is a function equivalent to f(x) = 5(1.9)3x?

f(x) = 34.29x
f(x) = 5(6.86x)
f(x) = 5(6.86)x
f(x) = 328.51x
The function equivalent to f(x) = 5(1.9)3x is f(x) = 5(6.86)x.
And of course, the Bot missed the first one
