Answer:
A
Step-by-step explanation:
The value of P is 3
Given general formula for a parabola is x2 = 4py ………….(a)
Also given that x2 = 12y …………..(b)
Equating (a) and (b), we get
x2 = 4py ≅ x 2 = 12y
⇒ 4py = 12y
Canceling the 'y' on either sides, we get
⇒ 4p= 12 p= 3
When the general formula for a parabola is x2 = 4py. The value of p in the equation x2 = 12y is 3.
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point and a line

Answer:
Step-by-step explanation:
1) Plot a dark (filled in) dot at -2.
Draw a horizontal line , represented by a dark horizontal line through y = 1, starting from the extreme left of y = 1, stopping at x = -2. This takes care of the first third of the graph.
2) Graph x on the interval -2 < x < 2 as follows: Draw a very light line with slope +1 through the origin. Next, draw a circle at both (-2, -2) and (2, 2). Do not fill in these circles. Now darken the line connecting (-2, -2) and (2, 2).
3) Graph the last part of this piecewise defined function as follows:
Plot a dark dot at (2, 2). Starting at this dark dot, draw a dark horizontal line to the right as far as the edge of graph. This takes care of f(x) = x for x ≥ 2.

9 goes in 36 4 times (the negative is included because it was a negative to begin with.
