Best ResponseYou've already chosen the best response.0take what ever is under the root sign from the quadratic formula: \[Dis =b^24ab\] this will give you clues as to how many roots the parabola has

Best ResponseYou've already chosen the best response.0the equation you have listed: \[y= 0.2x^2+1.62x+4\] is not the quadratic equation, but rather the standard form of a quadratic function

Best ResponseYou've already chosen the best response.1match your equation to the standard from \[ a x^2 +b x+c =0 \] in your case a= 0.2, b=1.62 and c=4 now use the formula (see Mathmuse post) See http://www.mathwarehouse.com/quadratic/discriminantinquadraticequation.php
