WebNov 16, 2024 · Solution For h(t) = 3√t +12t −2t2 h ( t) = t 3 + 12 t − 2 t 2 evaluate each of the following limits. lim t→−∞h(t) lim t → − ∞ h ( t) lim t→∞h(t) lim t → ∞ h ( t) Solution For problems 3 – 10 answer each of the following questions. (a) Evaluate lim x→−∞f (x) lim x → − ∞ f ( x) (b) Evaluate lim x→∞f (x) lim x → ∞ f ( x) WebAs x goes to infinity, the denominator goes to infinity, so the whole fraction goes to zero and the square root of zero is zero, so f (x) goes to zero. As x goes to infinity, the denominator goes to negative infinity, but we can't take the square root of a negative number, so f (x) doesn't have a limit as x goes to infinity.

The idea is to take out the higher power of 'x' in the denominator first. If the x squared is under a radical, take that out so you're left with just 'x'. After this, divide every term by 'x'. Once you are finished with this, you can rewrite the equation. detroit lions playoff win
