Answer:
Option D. [4,9]
Explanation:
we know that
The range of a function is the complete set of all possible resulting values of the dependent variable (output values), after we have substituted the domain (input values)
In this problem we have
The domain of the function (input values or independent variable) is the interval [2,3,4]
The range of the function (output variable or dependent variable) is the interval [4,9]
