determiningTheFunctionDomain
-3A^2+A=0
a = -3; b = 1; c = 0;Δ = b2-4acΔ = 12-4·(-3)·0Δ = 1The delta value is higher than zero, so the equation has two solutionsWe use following formulas to calculate our solutions:$A_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$A_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1}=1$
$A_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-3}=\frac{-2}{-6} =1/3$
$A_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-3}=\frac{0}{-6} =0$
