What the x coordinate?

x=-2

Step-by-step explanation:

If the question is asking for the intersection point, the answer is x=-2 or (-2,1) depending on if the teacher is asking for the intersection or value of x where it itersects

If the question is asking what the equation of the parabola is I would guess it is (x+1/2)^2 -4

I say go with x=-2 though

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

a is the correct
