Question

Which graph shows a polynomial function, f, such that f(x)→ ∞ as x→ -∞ and f(x) →∞ as x→∞ ?

Answer 1

F(x) means y

so f(x)→ ∞ as x→ -∞ and f(x) →∞ as x→∞ means
as x goes to the left y goes up infinitely
as x goes the the right, y goes up intinitely

that would be the 4th graph
the parabola opening up
