Answer

Please see the graph.

Work Step by Step

$y=5-4x+12x^2$ $y=12x^2-4x+5$ $a=12$, $b=-4$, $c=5$ $x=(-b±\sqrt {b^2-4ac})/2a$ $x=(-*-4±\sqrt {(-4)^2-4*12*5})/2*12$ $x=(4±\sqrt {16-240})/24$ $x=(4±\sqrt {-214})/24$ Since we have a negative square root, we have two complex roots for the equation.
