Question

Let g(x) be the indicated transformation .Write the rule for g(x) f(x)=x+2 reflection across the y-axis

Answer 1

The given function is

$f(x)=x+2$

The transformation is a reflection across the y-axis. This transformation is defined as

$g(x)=f(-x)$

Therefore, the transformed function is

$g(x)=-x+2$
