Answer:
2S = F
1.5R = S or R = S/1.5
So flour F and sugar S and raisins R
F + S + R = 550
2S + S + S/1.5. = 550
3S + 1.5S + S = 550*1.5
5.5 S = 550*1.5
S = 100*1.5
S = 150
R= 100
And so flour ie, F = 300
The discontinuity occurs when the denominator is equal to zero, as it has "infinite" slope, and thus is not a real value or point.
x^2+x-12
x^2+4x-3x-12
x(x+4)-3(x+4)
(x-3)(x+4)
So discontinuities occur when x=-4 and x=3
