Question

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

(–1, 0)

(0, –1)

(0, 1)

(1, 0)

Answer 1

i think D

Answer 2

Note that the vertex of y = |x| occurs at (0, 0).

Then since y = |x + 1| is just y = |x| shifted to the left by 1 unit, the vertex of y = |x| will also be shifted to the left by 1 unit.

Therefore, the vertex of y = |x + 1| is (0 - 1, 0) = (-1, 0).
