Fill in the blanks. Enter the vertex as an ordered pair. Remember to carefully consider the signs as you determine the coordinates of the vertex. Enter the axis of symmetry as an equation. Then graph the parabola given in vertex form by first plotting the vertex and then plotting a second point. standard form: f(x)=-x^2-8x-15

Fill in the blanks. Enter the vertex and y-intercept as ordered pairs and the axis of symmetry as an equation. Then graph the parabola given in standard form by first plotting the vertex and then plotting a second point. standard form: f(x)=-x^2-8x-15. does the parabola open up or down? what is the vertex? what is the y-intercept? what is the equation of the axis of symmetry? graph the parabola.
