Y=x^2-2x-4 parabola
Y=x^2-2x-4 parabola-By the formula given above, the xvalue of the vertex of the parabola is x=b/(2a)=(4)/(2(2))=1 The yvalue is found by substituting 1 for x into the equation y=2x^24x3 to get y = 2(1)^2The focal length is found by equating the general expression for y `y=x^2/(4p)` and our particular example `y=x^2/2` So we have `x^2/(4p)=x^2/2` This gives `p = 05` So the focus will be at
