find g(x) where g(x) is the reflection across the x-axis of f(x)=6x-2. write your answer in the form mx+b where m and b are integers

Question

find g(x) where g(x) is the reflection across the x-axis of f(x)=6x-2. write your answer in the form mx+b where m and b are integers

Answer 1

f(x) = 6x - 2

g(x) = -f(x) = -6x + 2

Answer 2

g(x) = f(-x)

g(x) = 6(-x) - 2

g(x) = -6x - 2
