Question

Which of the following describes the function shown in the table below?

Answer 1

The answer is B, the Y is decreasing less and less while the X values stay constant

Answer 2

Answer:

B

Step-by-step explanation:

Exponential function: $y = e^{kx}$, where k is a constant. Taking natural logarithm in both sides:

$y = e^{kx} => ln \, y = ln (e^{kx}) => ln\, y = kx \, ln\, e => \frac{ln\, y}{x} = k$

In figure attached the constant k is obtained. In conclusion, the function is exponential with constant rate of decay.
