Solve the equation graphically by finding x-intercepts.
-$$| x + 8 | = 1$$
A) $x = - 9$ or $x = 9$
B) $x = - 9$ or $x = - 7$
C) $x = 7$ or $x = - 7$
D) $x = - 9$ or $x = 0$

Question

Quizplus · Accepted Answer

The equation $| x + 8 | = 1$ can be solved by considering the two cases for the absolute value: $x + 8 = 1$ and $x + 8 = -1$. Solving these gives $x = -7$ and $x = -9$, respectively.
