Select the function whose end behavior is described by f(x) approaches infinity as x approaches infinity and f(x) approaches neg. infinity as x approaches neg. infinity

Question

Select the function whose end behavior is described by f(x) approaches infinity as x approaches infinity and f(x) approaches neg. infinity as x approaches neg. infinity
a. f(x)= 7x^9 - 3x^2 - 6
b. f(x)= -1/2x^3
c. f(x)= x^6 - 3x^3 - 6x^2 + x - 1
d. f(x)= -5x^4 - 3/2
i got no clue

oobleck · Accepted Answer

any polynomial of odd degree, with positive leading coefficient, will satisfy these conditions. Think of the graphs of y=x, y=x^3, etc. So, choose (a)
