Absolute Value Functions and Translations

Question 10 • FL-1200310-Algebra 1 A

The graph of f(x) = |x| is translated 6 units to the right and 2 units up to form a new function. Which statement about the range of both functions is true?

Answer
A
The range is the same for both functions: {y | y is a real number}.
B
The range is the same for both functions: {y | y > 0}.
C
The range changes from {y | y > 0} to {y | y > 2}.
D
The range changes from {y | y > 0} to {y | y > 6}.

Explanation

The range of f(x) = |x| is y ≥ 0, because absolute value is never negative and reaches 0. Moving the graph 2 units up raises every output by 2, so the new range is y ≥ 2; moving it right does not change the range. Choice C gives the intended change, though its strict inequalities should be inclusive: the ranges include 0 and 2, respectively.
