Let g(x) be the reflection of f(x) = 3x + 2 in the x-axis. What is a function rule for g(x)?

g(x) = 3x – 2
g(x) = –3x – 2
g(x) = 3x + 2
g(x) = –3x + 2

Refrection of a function in the x-axis give the negative of that function.

Refrection of f(x) = 3x + 2 in the x-axis gives -f(x) = -(3x + 2) = -3x - 2

Therefore, g(x) = -3x - 2
