Write an equation that represents a vertical translation 7 units down of the graph of g(x)=|x|.
polet [3.4K]

Answer:

g(x) = |x| - 7

Step-by-step explanation:

Given the parent function, g(x) = |x|, and its vertex at (0, 0):

Vertical translations: g(x) = |x| + <em>k</em> where:

<em>k</em> > 0, shifts up |<em>k </em>| units

<em>k</em> < 0, shifts down |<em>k </em>| units

Thus, a vertical translation of the parent graph can be represented with the following absolute value function:

g(x) = |x| - 7

where the vertex occurs at point, (0, -7).
