Which is true about a Quadratic Function? a. quadratic function requires an exponent of "2" when in standard form.

b. quadratic function requires an exponent of "1" when in standard form.

c. quadratic function requires a constant.

d. quadratic function looks like a "V" shape when drawn.

the answer is

The quadratic function f(x) = a(x - h)2 + k, a not equal to zero, is said to be in standard form. If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h,k)

Step-by-step explanation:

sorry if its wrong ): hope it helps (:

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.
