Which of the following describes the end behavior of the function ƒ(x) = –5x3 + 3x2 + x – 9?

A)

As x → –∞, y → +∞ and as x → +∞, y → –∞

B)

As x → –∞, y → –∞ and as x → +∞, y → +∞

C)

As x → –∞, y → –∞ and as x → +∞, y → –∞

D)

As x → –∞, y → +∞ and as x → +∞, y → +∞

Respuesta :

Answer:

A

Step-by-step explanation:

f(x)=-5x³+3x²+x-9

leading coefficient is negative and it is of odd degree.

so it starts from above onthe left  and ends at the bottom ont he right.
