Rewrite the equation in term of ( x) and ( y). ( f(t)=-(t-2)(t-15)) Rewrite the equation in vertex form. ( y=-((t-(17)/2))^2+(169)/4) Use the vertex form, ( y=a((t-h))^2+k), to determine the values of ( a), ( h), and ( k). ( a=-...
In order to find the focus of a parabola, you must know that the equation of a parabola in a vertex form is y=a(x−h)2+k where a represents the slope of the equation. From the formula, we can see that the coordinates for the focus of the parabola is (h, k+1/4a). Where ...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter
