Question

graph y=lxl -1

Answer 1

first do you know what y=|x| looks like?

Answer 2

is it linear?

Answer 3

Re-write it as:
\[y+1 = |x|\]
And recognize it as a transformation of the graph y=|x| where your origin has been shifted up one unit.

Answer 4

ok so would the -1 shift it to the left?

Answer 5

No, it's shifting along the y-axis.
