1 point 17) Which equation describes a parabola that opens downward, is congruent to y = x*2, and has its vertex at (0, 3)?Answer Correct option is B y = 0 The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves y2 2x = 0 y2 = −2x is the equation of a parabola It is in the form of y2 = 4ax So axis of parabola will be xaxis ( y = 0) as shown in the given figure Answer verified by TopprSubstitute the values of a a, d d, and e e into the vertex form a ( x d) 2 e a ( x d) 2 e 4 x 2 4 x 2 4 x 2 4 x 2 Set y y equal to the new right side y = 4 x 2 y = 4 x 2 y = 4 x 2 y = 4 x 2 Use the vertex form, y = a ( x − h) 2 k y = a ( x h) 2 k, to determine the values of a a, h h, and k k
The equation of a parabola can be converted into the vertex form y = a(xh) 2 k, where h = xcoordinate of vertex, and k = ycoordinate of vertex Also, if a is positive, the parabola opens upward Also, if a is positive, the parabola opens upward Correct answer to the question Find the vertex of the parabola by completing the square x^26x8=y hmwhelpercom For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P', the coordinates of P' are (5,4)Notice that the ycoordinate for both points did not change, but the value of the xcoordinate changed from 5 to 5 You can think of reflections as a flip over a designated line of reflection

Use traces to sketch the surface z = 4x2 y2 Solution If we put x = 0, we get z = y2, so the yzplane intersects the surface in a parabola If we put x = k (a constant), we get z = y2 4k2 This means that if we slice the graph with any plane parallel to the yzplane, we obtain a parabola that opens upward Similarly, if y = k, 2the trace is z = 4x k2, which is again a parabola that opensIf your parabola only crosses the xaxis at a single point, a, then that point will be the vertex of the parabola The equation of such a parabola will be mathy=(xa)^2/mathThe set of points (x, y) whose distance from the line y = 2 x 2 is the same as the distance from (2, 0) is a parabola This parabola is congruent to the parabola in standard form y = K x 2 for some K which is equal to

Each parabola is affine congruent to P 0 y 2 = x Each ellipse or circle is affine congruent to E 0 x 2 y 2 = 0 Each hyperbola is affine congruent to H 0 xy = 1 proof of theorem AC2 Since two curves which are affine congruent to the same curve are affine congruent, we see that theParabola congruent to y = ax2 xintercepts at x = m and x = n (aka the "zeros" of the quadratic function) Regardless of the form, a parabola opens up when a > 0 and opens down when a < 0, with the axis of symmetry passing through the vertex of the parabolaWe can find the parabola's equation in vertex form following two steps Step 1 use the (known) coordinates of the vertex, ( h, k), to write the parabola 's equation in the form y = a ( x − h) 2 k the problem now only consists of having to find the value of the coefficient a Step 2 find the value of the coefficient a by substituting

Six congruent copies of the parabola $y = x^2$ are arranged in the plane so that each vertex is tangent to a circle, and each parabola isThe equation of this new parabola is thus y = x 2 9 The vertex of this parabola is now (0, 9), but it has the same axis of symmetry Similarly, the basic parabola becomes y = x 2 − 9 when translated down 9 units, with vertex (0, 9) We can confirm thisGenerally, only the higher level of high school maths contain locus questions (especially year 11) As discussed earlier, we have to deal with the locus form of quadratics, which is given as $$(xh)^2=±4a(yk)$$ We have already seen that (h,k) represent the vertex of the quadratic
