\[ y= \color{chocolate}{-f}(x)\] what does that tell us?

jnlkmnjkm:

go right

Florisalreadytaken:

no -- whenever we are given that, we have to flip VERTICALLY

Florisalreadytaken:

eg. D's coordinates are (0,-6) -- by flipping it vertically, we would get the opposite, so from negative, it turns positive

jnlkmnjkm:

0,6?

Florisalreadytaken:

yes!

jnlkmnjkm:

c turns into 1, -1?

Florisalreadytaken:

the x axis stays the same -- its just the y axis which changes, in our case

jnlkmnjkm:

c turns into -1, -1?

Florisalreadytaken:

yes!
