Question

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

Answer 1

a reflection of f(x) on x-axis = -f(x) = -(3x+2) = -3x -2

Answer 2

thank you . .

Answer 3

whereas reflection of f(x) on y-axis would be f(-x) = 3(-x) +2 = -3x+2
