Question

lim (2x^4 + 20x^3/1000x^3 + 4)
x → −∞

is it 1/4? or -∞

Answer 1

I have a feeling it's +infinity. Because, in your function, your x^3 terms are divided by each other, that means those variables will cancel out. So you're get the limit of (2x^4 + constant). If I remember the behavior of an x^4 function, both the left and the right end extend to positive infinity.

Answer 2

\[2x^{4} + \frac{ 20x^{3} }{ 1000x^{3} } + 4\]

Answer 3

Is that the function?

Answer 5

no its (2x^4 +20x^3)/(1000x^3 + 4)
