TIMED Consider f (x) = StartFraction 7 x squared + x + 1 Over x Superscript 4 Baseline + 1 EndFraction

Which statement correctly uses limits to determine the end behavior of f(x)?

Limit of StartFraction 7 x squared + x + 1 Over x Superscript 4 Baseline EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 1 Over 1 EndFraction as x approaches plus-or-minus infinity, so the end behavior of the function is that as x ± ∞, f(x) → 1.
Limit of StartFraction 7 x squared + x + 1 Over x Superscript 4 Baseline EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 7 Over x squared EndFraction as x approaches plus-or-minus infinity, so the end behavior of the function is that as x ± ∞, f(x) → 0.
Limit of StartFraction 7 x squared + x + 1 Over x Superscript 4 Baseline EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 7 Over x squared EndFraction as x approaches plus-or-minus infinity, so the end behavior of the function is that as x ± ∞, f(x) → 7.
Limit of StartFraction 7 x squared + x + 1 Over x Superscript 4 Baseline EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 7 x squared Over 1 EndFraction as x approaches plus-or-minus infinity, so the end behavior of the function is that as x ± ∞, f(x) → ∞.
