Which graph represents the function p(x) = |x – 1|?

The last one

Step-by-step explanation:

Your equation is p(x) = |x - 1|

The function equation can be represented by f(x) = a|x - h| + k

To find the vertex, you have to find (h,k)

In the equation p(x) = |x - 1|, 1 is h [since its (+h,k) not (-h,k)]

k is 0 since there is no +k after |x-1|.

So, your vertex will be at (1,0)

Thus, the answer is the last graph.
