Question

If f(x) = 2x + 7, given the domain of (0, 1, 2). What is the range?

A. {7, 9, 11}
B. {7, 9, 14}
C. {9, 11, 15}
D. {9, 11, 13}"

Answer 1

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}.
