Which statement correctly describes the end behavior of f(x) = -9x^4 + 3x^3 + 3x^2 - 1?

As x goes to infinity, f(x) goes to infinity, and as x goes to negative infinity, f(x) goes to infinity.

As x goes to infinity, f(x) goes to negative infinity, and as x goes to negative infinity, f(x) goes to infinity.

As x goes to infinity, f(x) goes to infinity, and as x goes to negative infinity, f(x) goes to negative infinity.

As x goes to infinity, f(x) goes to negative infinity, and as x goes to negative infinity, f(x) goes to negative infinity.

#4: "As x goes to infinity, f(x) goes to negative infinity, and as x goes to negative infinity, f(x) goes to negative infinity."

(Both end behaviors trend toward infinity)

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
