Question

What are the values of a, b, and c in the function? List them in order with commas, such as 1,-2,3.

y = -2x2 + 5x - 4

Answer 1

\(y = -2x^2 + 5x - 4\) vs the form of \(y = ax^2 + bx + c\)

Note: sign does matter!

Answer 2

Thanks!:)

Answer 3

So that made sense now? Not a hard one, but if you do not know which abc they mean... then it suddenly becomes hard.

Answer 4

Yes, thanks for explaining.

Answer 5

np. I rather people get it than just get an answer. That way you will know it when it is used in later math classes. For example, calculus is about 10% new stuff and 90% doing everything before calculus!
