Answer:
x = 0 or x = 1
Step-by-step explanation:
f(x) = |x| - 4
g(x) = x³ - 4
f(x) = g(x)
|x| - 4 = x³ - 4
Add 4 to both sides.
|x| = x³
x = x³ or -x = x³
x³ - x = 0 or x³ + x = 0
x(x² - 1) = or x(x² + 1) = 0
x = 0 or x + 1 = 0 or x - 1 = 0
x = 0 or x = -1 or x = 1
x = -1 does not work, so we discard that solution.
Answer: x = 0 or x = 1
