Final answer:
The range of f(x) = 2x + 7 with a domain of (0, 1, 2) is {7, 9, 11}.
Step-by-step explanation:
To find the range of the function f(x) = 2x + 7, we need to substitute the given domain values of 0, 1, and 2 into the function and determine the corresponding output values.
f(0) = 2(0) + 7 = 7
f(1) = 2(1) + 7 = 9
f(2) = 2(2) + 7 = 11
Therefore, the range of the function is {7, 9, 11}. The correct answer is A. {7, 9, 11}.
