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

To visualise it, draw the line y=3x+2 You know for example that if x=2 y= 8 so the reflections gonna go through the same point but on the other side of the axis

so... g(x) = –3x – 2?

No, the y value will stay the same on the oppsite side, so it's g(x)= 3x+2

Think of the dot (2,8) if you want it's reclection the point on the other side is (2,8) try to draw it and you'll get the idea
