Question

limite de 4x + 1 / 2x2 + 5x - 1 x para menos infinito

Answer 1

lim (4x+1)/(2x²+5x-1)
x-->-∞

lim x²(4/x+1/x²)/x²(2+5/x-1/x²)
x-->-∞

lim (4/x+1/x²)/(2+5/x-1/x²)
x-->-∞

= (4/(-∞)+1/∞)/(2+5/(-x)-1/∞)

= (0+0)/(2+0-0)  =0/2=0 

Answer 2

Boa tarde

lim (4x + 1)/(2x² + 5x - 1) = lim (0)/(4x + 5) = 0 
x-->-∞                                 x-->-∞
