Question 16
den301095 [7]

Answer:

Statement B and D are correct.

Step-by-step explanation:

The number of minutes Gabriel spends grading essays can be presented as a function: f(x) = 4x, where x is the number of graded essays and 4 is the number of minutes Gabriel spends on grading each essay.

By definition, domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

So in this case, domain of f(x) is the set of all values of x which is an integer going from 0 to 105. Statement D is accurate.

Range of f(x) is the set of all values that f takes and can be calculated by multiplying 4 with (0,105), equal (0,420). Statement B is accurate.
