Question

What is the y-coordinate of the vertex of y = |–3x + 6| – 2 ?

Answer 1

u mean y intercpt right?

Answer 2

The fact that the - rotates it and the 3 stretches it, it is only shifted 6 to the LEFT and 2 DOWN. So the coord is (-6,-2).
So the y coordinate is -2.

Answer 3

y=|-3(x-2)|-2=|-3|*|x-2|-2=3|x-2|-2

Answer 4

but we didn't have to really do all of that since we were just looking for y part

Answer 5

"The fact that...is irrelevant, it is only..."
Good point myiniaya. Its (2,-2) lol.
