Final answer:
The key features of the exponential function y= 2(3)^x include the domain, range, y-intercept, and asymptote.
Step-by-step explanation:
The key features of the exponential function y= 2(3)^x are:
- Domain: The domain of the function is the set of all real numbers, as there are no restrictions on x.
- Range: The range is the set of all positive real numbers, as 2(3)^x can never be negative or zero.
- Y-Intercept: The y-intercept is the point where the graph of the function intersects the y-axis. In this case, when x=0, y=2(3)^0=2.
- Asymptote: As x approaches negative infinity, the value of 2(3)^x approaches 0. Therefore, the x-axis acts as a horizontal asymptote.
