Answer:

See explanation

Explanation:

Vertex: -b/2a = 8/4 = 2. Plug 2 back into the equation to get (2, -2)

y-intercept: plug 0 for all the x values to get 6. The y intercept is (0,6)

x intercept: factor the equation:

2(x^2 - 4x + 3)

2(x-3)(x-1) <— by splitting the middle variable

so the x intercepts are (x-3) and (x-1) or 3 and 1.

Axis of symmetry : 2 (the x value of the vertex)

Domain: ARN ( all real numbers)

Range: ARN except y cannot be less than -2.

To graph you simply just plug in x values in a table and get the y values. Then plot them on the graph and draw a smooth curve.
