½x-5=3 x=16 ¼*16²-5*16+6=3*16+p p=-58 het is een dalparabool, dus hij raakt de grafiek in de grootste waarde van p dus p<-58 |

y=(-1/2*p)²-1/2*p²+5=1/4*p²-1/2*p²+5=-1/4*p²+5. Invullen van x en y in de vergelijking van de lijn geeft: -1/4*p²+5=-p+2. Links en rechts met -4 vermenigvuldigen geeft: p²-20=4*p-8, dus p²-4*p-12=0, dus (p+2)(p-6)=0, dus p+2=0 of p-6=0, dus p=-2 of p=6.
