Answer:
Well I think it is A because domain is the x values.
Step-by-step explanation:
So when you plug this in your calculator (mine is a ti-84 plus ce) you would hit graph. After it graphs it press Zoom, 0 to center it then press 2nd, trace which pulls up parabola menu's. Press 0 and find the left bound, right bound and then press enter which would give you x values of 2.9375 < t< 6
At the same time I don't know if this is right. I never really excelled at parabolas just trying to help.

Here:
perimeter = 174 units
or, 2(PQ+QR) = 174
or, 2(4y+3+3y) = 174
or, 2(7y+3) = 174
or, 14y+6 = 174
or, 14y = 174 - 6
or, y = 168 / 14
Therefore, y = 12
So,
PQ = 4 x 12 + 3
= 51 units
