vertical asymptotes x = - 4 ,
horizontal asymptote y = 0
Explanation:
Vertical asymptotes occur as the denominator of a rational function tends to zero. To find the equation/s let the denominator equal zero.
solve : (2x - 3 )(x +4) = 0
# rArr x = -4 , x = 3/2" are the asymptotes "# Horizontal asymptotes occur as
#lim_(xto+-oo) f(x) to 0 # When the degree of the numerator < degree of the denominator , as is the case here the the equation is always
y = 0Here is the graph of f(x).
