Parabola congruent to y=x^2
Parabola congruent to y=x^2-Rather than using implicit differentiation to find the derivative of y with respect to x, we should simplify the expression and put x in terms of y y = (x^2)/4a or f(x) = (x^2)/4a Using the power rule of differentiation, we get f'(x) = (2*x^(2–1)Hand 9 Write the equation for each parabola with the given information mark each a) Congruent to y = 2x opens up, with a vertex of (51) > Congruent to y =(x 2), maximum vukue of 4, equation of asis of symmetry * = 2 10 Write the equation of the parabola with given vertex, if it passes through the given pointcz a) vertex (0,1), passing through (29) b) vertex (2,4), passing through (42

Consider a parabola P that is congruent to y=x 2, opens upward and has a vertex of (1,3) Now find the equation of the new parabola that results it P isThe axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves The axis of symmetry always passes through the vertex of the parabola The x coordinate of the vertex is the equation of the axis of symmetry of the parabola For a quadratic function in standard form, y = ax2 bx c , the axis ofAssuming that, in your picture, the parabola crosses the x axis at two points, a and b then the factored form of your parabola will be y = (x − a) (x − b) If 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 y = (x − a) 2

Write equations for two parabolas that are congruent to the parabola given by y = x 2, and explain how you determined your equations Answer (Student answers will vary) The parabolas given by y = (x – 2) 2 and y = x 2 – 3 are congruent to the parabola given by y = x 2 The first parabola is translated horizontally to the right by two units and the second parabola is translated down by 3 units, so they each are congruent to the original parabolaThe Vertex of the Parabola The Vertex of the Parabola is the point where the parabola abruptly changes direction In this case, we need to find the equation of the graph which is congruent toThe focus of a parabola can be found by adding to the ycoordinate if the parabola opens up or down Substitute the known values of , , and into the formula and simplify Find the axis of symmetry by finding the line that passes through the vertex and the focus Find the directrix
