Answer:

Step-by-step explanation:
We know that the vertex(lowest point) of
is
.
By inspection, we can see that the vertex of the graph is
.
So, the lowest point of
is
, which means 
Since there are a total of 48 beads and each bead will either be blue or yellow, in order to find out how many of each colour bead she will use, do the following:

48 - 16 = 32
Therefore, she will use 16 yellow beads and 32 blue beads.
