Write the function in vertex form. {eq}\displaystyle y = - x^2 - 3x - 6 \\y = \boxed{\space} {/eq} Equation of a Parabola in Vertex Form The equation of a parabola can be expressed in numerous ways. In a general sense, a standard form of a parabola is given b...
Move the constant on the left-hand side of the equation back over to the right by adding or subtracting it. In the example, subtract 18 from both sides, producing y = 2(x + 2)^2 - 18. The equation is now in vertex form. In y = 2(x + 2)^2 - 18, h = -2 and k = -1...

Write the equation of the parabola in standard form and find its vertex. y= -2x^2 + 4x + 8 = 0 Graph the paraboloid z = 4 x^2 + y^2 and the parabolic cylinder: y = x^2. Find the equation of the intersection. Let f(x)= 2x^2 - 10x + 12. a. Comp...
【解析】Because the verter of the parabola is at(h,k)=(1,2), the equation has the formf(x)=a(x-1)^2+1 . Substitute for h and k in standard form.Because the parabola passes through the point(,0), it follows that f(0)=0. So,0=a(0-1)2+2→a=-2 Substitute o for ; so...
Just as a quadratic equation can map a parabola, the parabola's points can help write a corresponding quadratic equation. With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and
