Problem

This is the graph of y, equals, 6, vertical bar, x, plus, 4, vertical bar, minus, 4.
An absolute value function graph on an x y coordinate plane. The x- and y- axes scale by one. The graph has a vertex at (negative four, negative four). It decreasing from the interval of negative infinity to negative four passing through the point (negative five, two) and increases from the interval negative four to infinity passing through the point (negative three, two).
Given that x, approximately equals, minus, 5 is an approximate solution to 6, vertical bar, x, plus, 4, vertical bar, minus, 4, equals, 3, use the graph to find another approximate solution.
Round your answer to the nearest integer.
x, approximately equals
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
