Question

y=-lx+1l opens up or down? Identify vertex and tell wether wider narrower or same width as y= l xl

Answer 1

down, if its negative on the outside it opens down, it doesn't matter inside

Answer 2

oh right, but it still opens down

Answer 3

vertex: (0,1) same width opens down

Answer 4

YES IT DOES
its has a vertex

Answer 5

liamarie u got it

Answer 6

wrong polrek. there is a vertex. absolute value means any x value will go same direction.

x isn't being affected (meaning it's not being x'd by anything) so it will have the same width.

Answer 7

the graph opens down, with the vertex at (-1,0). Same common slope as the parent function, as the coefficient in front of the absolute value is -1.

Answer 8

^that one's correct

Answer 9

remember, the vertex is just when x=0, so plug 0 in for x and solve. that'll give you the y value and the vertex.

Answer 10

A lot of crazy posts in this one

Answer 11

The general equation is \[y=a \left| x-h \right|+k\], where the vertex is (h,k)
