Question

One more question. Which of the following graphs represents a function that has a negative leading coefficient? Check all that apply.

I think it's A and B. Am I right?

Answer 1

it was A, B, and C.

Answer 2

o looking at what you have

A is a degree 3 polynomial

B is a degree 2 polynomial


C is a degree 1 polynomial

D is a degree 2 polynomial...

now a basic rule of thumb is

for odd degree polynomials with a negative leading coefficient they start in upper left and finish in lower right

for even degree polynomials the negative leading coefficient means the the positve has been turned upside down.

hope it helps
