Answer:
A. {1, 7, 11}
Step-by-step explanation:
The constant in the equation is 1, so that is the value when x=0. No answer choice can be correct unless it includes the value 1. The only viable choice is A.
_____
If you want to go to the trouble to evaluate the expression for the different values of x, you can. It often works well to rewrite the expression to "Horner form":
(2x -1)x +1
For x = -2, this is (2(-2) -1)(-2) +1 = (-5)(-2) +1 = 11
For x = 0, this is 1
For x = 2, this is (2(2) -1)(2) +1 = (3)(2) +1 = 7
So, the range for the given domain is {1, 7, 11} . . . . . matches choice A
Answer:
x=6f-7 is the correct answer.
