Question

use the graph of the parabola to fill in the table. (a) does the parabola open upward or downward? upward downward (b) find the intercept(s). for both the x - and y -intercept(s), make sure to do the following. - if there is more than one, separate them with commas. - if there are none, select
one\. x -intercept(s): -2,4 y -intercept(s): -8 (c) find the coordinates of the vertex. vertex: (1, -9) (d) find the equation of the axis of symmetry. equation of axis of symmetry:

Explanation:

Step1: Recall axis - of - symmetry formula

The axis of symmetry of a parabola passes through its vertex. For a parabola with vertex $(h,k)$, the equation of the axis of symmetry is $x = h$.

Step2: Identify the x - coordinate of the vertex

The vertex of the parabola is given as $(1,-9)$. The x - coordinate of the vertex is $h = 1$.

Answer:

$x = 1$
