Question

(a): FInd the coordinates of the vertex

(b): Find the intercept(s). For both the x- and y-intercepts, make sure to do the following:
-If there is more than one, seperate them with commas.
-If there are none, write "None"

x-intercept(s): __
y-intercept(s):__

(c): Find the equation of the axis of symmetry
Equation of axis of symmetry: ___

Answer 1

In this question, you just need to locate and write the coordinates.


a) Vertex is the maximum or the minimum of the parabola. In this case, the point's coordinates are (2, -9).


b) Intercepts are the points where the parabola intersects with the axes.

x-intercepts for this parabola are: (-4, 0), (8, 0).

y-intercept for this parabola is: (0, -8).


c) The AoS is the vertical line which goes through vertex and divides the parabola in half.

In this case, the axis of symmetry is x=2.
