Rewrite the equation y=2|x−2|+4 as two linear functions f and g with restricted domains.
2 answers:
Answer:
f(x) = -2x + 8, x < 2
g(x) = 2x, x 》2
Step-by-step explanation:
|x - 2| is:
x - 2, for x 》2
-x + 2, for x < 2
For x < 2,
f(x) = 2(-x + 2) + 4
f(x) = -2x + 8
For x 》2,
g(x) = 2(x - 2) + 4
g(x) = 2x
Answer:
f(x) = -2x + 8, x < 2
g(x) = 2x, x 》2
