Question: A function is described by the equation f (x ) = 2x + 1. The replacement set for the independent variable is {0, 2, 3, 4}. Which of the following is contained in the corresponding set for the dependent variable? A ) 9 B ) 2 C ) 3 D ) 15 Steps to derive 1 Independent variable is the input and the dependent variable is the output of the function.
2 Substitute the values of x and find the corresponding values of f (x ).3 For x = 0, f (0) = 2(0) + 1 = 1 [Substitute x = 0 in f (x ) = 2x + 1.]4 For x = 2, f (2) = 2(2) + 1 = 5 [Substitute x = 2 in f (x ) = 2x + 1.]5 For x = 3, f (3) = 2(3) + 1 = 7 [Substitute x = 3 in f (x ) = 2x + 1.]6 For x = 4, f (4) = 2(4) + 1 = 9 [Substitute x = 4 in f (x ) = 2x + 1.]7 The set for the dependent variable is {1, 5, 7, 9}.8 Among the choices, the value 9 is in the dependent variable set.Hence the right answer is Option A Click Here To Go Back Few Other Questions - Identify the missing number in the pattern.9, 27, 81, ___, 729, . . ...
