anonymous · Answer

which one has a negative "leading coefficient" ?

anonymous · Answer

i have no idea:(

anonymous · Answer

do you know what "leading coefficient" means? if not , i will tell you

anonymous · Answer

thats why i dont understand these

anonymous · Answer

no

anonymous · Answer

the "leading coefficient" is the number in front of the term of highest degree
in this case that means the number in front of the $x^2$ term

anonymous · Answer

c?

anonymous · Answer

for example, in $y = 4x^2 – 6x – 3$ the leading coefficient is $4$ and in $	y = 8x + 5x^2 – 3$ the leading coefficient is $5$

anonymous · Answer

find the one where the leading coefficient is negative
