Y=x^2-4x 1 parabola 249151

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 the coordinates of point P into the equation written in step 1 and solving The parabolas y^2 = 4x and x^2 = 4y divide the square region bounded by the lines x = 4, y = 4 The parabolas y2 = 4x and x2 = 4y divide the square region bounded by the lines x = 4, y = 4 and the coordinate axes If S1, S2 and S3 are respectively the areas of these parts numbered from top to bottom, then S1 S2 S3 is equal to a = 1 Persamaan parabola y = ax 2 bx c adalah sebagai berikut y = x 2 – 4x c melalui titik (0,1) 1 = 0 2 – 4(0) c c = 1 Maka bisa dihitung y = x 2 – 4x 1 x p = b/2a = (4)/2(1) = 2 dan y p = (2) 2 – 4(2) 1= 5 Sehingga titik puncak parabolanya yaitu (2,5) Jadi jawabannya yaitu E Soal 4 (UN 08)
