Step-by-step 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.
