Note: this exercise can be downloaded as a worksheet to practice with: So, we will substitute x=3 and y=5 How to find the equation of a parabola using its vertex. ; What are the points of intersection of the line with equation 2x + 3y = 7 and the parabola with equation y = - 2 x 2 + 2 x + 5? $$y=a\begin{pmatrix}x-h\end{pmatrix}^2+k$$, $$y = 4 \begin{pmatrix}x-2\end{pmatrix}^2-7$$, $$y = \begin{pmatrix}x-2\end{pmatrix}^2+ 3$$, $$y = -3 \begin{pmatrix}x+3 \end{pmatrix}^2+1$$, $$y = 12 \begin{pmatrix}x-1\end{pmatrix}^2-4$$, $$y = 2\begin{pmatrix}x+1 \end{pmatrix}^2+1$$, $$y = 3 \begin{pmatrix}x-2\end{pmatrix}^2+1$$, $$y = -2\begin{pmatrix}x-3\end{pmatrix}^2+ 5$$, $$y = 2 \begin{pmatrix}x+4 \end{pmatrix}^2-3$$, $$y = - \begin{pmatrix}x+1\end{pmatrix}^2-3$$, $$y = 4\begin{pmatrix}x-3 \end{pmatrix}^2-5$$. VERTEX OF THE PARABOLA - In both equations, coordinates (h,k) denotes vertex of the parabola, which is the point where the axis of symmetry intersects the line of a parabola. Section 4-2 : Parabolas. 3. 1) … �1�jm�E�U1f�ٌ��A���`�nZI��;9Ц�beS'Q{��I�]Y��X\$k Depends on whether the equation is in vertex or standard form Finding Vertex from Standard Form The x-coordinate of the vertex can be found by the formula $$\frac{-b}{2a}$$, and to get the y value of the vertex, just substitute $$\frac{-b}{2a}$$, into the
