Which statements are true of the function f(x) = 3(2.5)x? Check all that apply.The function is exponential.The initial value of the function is 2.5.The function increases by a factor of 2.5 for each unit increase in x.The domain of the function is all real numbers.The range of the function is all real numbers greater than 3.

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.
