Question 7 • Algebraic Reasoning

Which function is a translation of the parent absolute value function?

Answer
A
f of x is equal to 2 absolute value of x
B
f of x is equal to start absolute value x plus 6 end absolute value
C
f of x is equal to negative 4 absolute value of x
D
f of x is equal to absolute value of x

Explanation

The parent absolute value function is f(x) = |x|. A translation shifts its graph horizontally or vertically without changing its shape, as in |x + 6|. Choices A and C change the graph’s steepness or direction by multiplying |x|, while B is the unchanged parent function. Therefore, the translated function is choice D, f(x) = |x + 6|.
