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

Best ResponseYou've already chosen the best response.1To 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

Best ResponseYou've already chosen the best response.0so... g(x) = –3x – 2?

Best ResponseYou've already chosen the best response.1No, the y value will stay the same on the oppsite side, so it's g(x)= 3x+2

Best ResponseYou've already chosen the best response.1Think 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
