What are the vertices of δpqr? a.) pq, qr, and pr (lines above these letters) b.) p, q, and r c.) ∠p, ∠q, and ∠r d.) none of these. there was no image attached to this question, no graph, no triangle, nothing. (this question probably doesn't even need one so)

The vertices is where "two lines meet together". This pretty much means the points in a triangle, for two sides meet in one point, which is generally where the angle is.

B. P, Q, and R is your answer, for those are the names of the vertices (where the two lines meet together).

hope this helps

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
