Question 77390 • High School Math 2 A
In f(x) = 3(2.5)^x, the variable is in the exponent, so the function is exponential. Its initial value is f(0) = 3(2.5)^0 = 3, and each increase of 1 in x multiplies the output by 2.5. The domain is all real numbers; the range is positive values greater than 0, not values greater than 3.
