For each of the following equations.
find the coordinates of the vertex of the curve it describes.
find the x− intercepts.
find the y− intercept.
find the equation of the line of symmetry.
use all this information to sketch the graph of the function.
y=8−2x2

See below in bold.

Step-by-step explanation:

y = 8 - 2x^2

This is a parabola which because the coefficient of x^2 is negative opens downwards.

It is symmetrical about the y axis and the vertex is (0, 8).

To find the x- intercepts put 8 - 2x^2 = 0 and solve for x:

2x^2 = 8

x^2 = 4

x = +/- 2.

The x-intercepts are  (-2,0) and (2, 0).

The y -intercept = vertex = (0, 8).

The equation of the line of symmetry is the y-axis = x = 0.
