Discriminant = sq root of b^2 - 4*a*c = sq root of 36 - 4*1*13 = sq root 36 -52 = sq root 36 -52 = sq root -16 There are no real solutions for this equation. Both roots are complex numbers.
B: because 11 times N will give you how much your cost would be . Example: 11*2= $22 if you bought 2 cds it would be $22. and its continuous cause youre going up at a constant rate.
