Show that there are no values of k for which the line y=3-2x can intersect the curve y=2x^2+kx+3
~~~~~~~~~~~~~~~~~~~~~~

The statement is WRONG.

The counter-example is k = 0 shown in the plot below.



Plots y = 2x%5E2%2B3 (red) and y = 3 - 2x (green)


What is the reason you post wrong problem to this forum ??

Please do not it in the future. Thanks.
