Answer

Final Answer: The range of the function f(x)=2x1 for the domain {3,1,2,4} is {7,3,3,7}

Steps

Step 1 :The function f is defined as follows for the domain given: f(x)=2x1, with domain = {3,1,2,4}

Step 2 :The range of a function is the set of all possible output values (y-values) which we get after substituting all the elements of a domain.

Step 3 :In this case, the domain is given as {3,1,2,4}. We can find the range by substituting these values in the function f(x)=2x1.

Step 4 :Substituting -3 into the function, we get f(3)=2(3)1=7

Step 5 :Substituting -1 into the function, we get f(1)=2(1)1=3

Step 6 :Substituting 2 into the function, we get f(2)=2(2)1=3

Step 7 :Substituting 4 into the function, we get f(4)=2(4)1=7

Step 8 :So, the range of the function f(x)=2x1 for the domain {3,1,2,4} is {7,3,3,7}

Step 9 :Final Answer: The range of the function f(x)=2x1 for the domain {3,1,2,4} is {7,3,3,7}
