Question

The graph of g(x) is the graph of f(x)=x+6 reflected across the x-axis.

Which equation describes the function g?


A) g(x)=x−6

B) g(x)=−x+6

C) g(x)=−x−6

D) g(x)=−6x−6

Answer 1

hi im doing this as well and im pretty sure its C. g (x) = -x - 6

Answer 2

When you reflect across the x axis, f(x) becomes -f(x) for all values of x: 
g(x) = -f(x)
g(x) = - (x + 6)
g(x) = -x - 6

Answer is C
