y = 3(2)^x

- Type: exponential growth (base > 1).
- y-intercept (x = 0): y = 3 → point (0, 3).
- Common ratio / growth factor (per unit increase in x): 2 (the function doubles when x increases by 1).
- Percent growth per unit: 100% increase each time x increases by 1.
- Horizontal asymptote: y = 0.
- Domain: all real numbers. Range: y > 0.
