anyway,
heres how the graph would look

hey, man I've checked my suitcase of graphs again and have to insist on E as the final go and not C

Here's why - we checked discriminant and it's not 0 (D=25). The only case when the graph touches x-axis at one point is when D=0 in all other cases D>0 there are always two x-intercepts, D<0 not any intercept ever

experts please comment whether it's C or E

true
and that is exactly why i got 2 intercept points as shown in the graph


I would stick to C because the two points are always the intercepts

Can someone please explain as to how we got the ratio
W : C : M = 25 : 10 : 22 from C : W = 5 : 11
it is really confusing.
