Answer:

Vertical asymptote is at # x = -1#
Slant asymptote is #y=4x-5#

Explanation:

#f(x) = (4x^2-x +2)/(x+1)#

Vertical asymptote is fomed when deniminator is zero.

# :. x +1= 0 or x = -1# So vertical asymptote is at # x = -1#

Here degree in numerator is #1# greater than degree in

denominator . So we have a slant asymptote which is found by

doing long division . By long division we find Quotient as

#y=4x-5# . So slant asymptote is #y=4x-5#
