Question

What is the vertex of y = |x + 1| ?

(–1, 0)

(0, –1)

(0, 1)

(1, 0)

Answer 1

Only two of those points lie on the curve... besides, just try graphing a few points ;-)
y - k = a|x - h|

Answer 2

I don't understand?

Answer 3

Questions like this will be a lot easier if you toy around with the problem first and learn... what is the difference between the plots for the curves y = |x| and y = |x + 1|?
