Question

help please. analyze the graph of the function f(x)=(x^2-9x-10)/(x+5). What is the domain of F(x)?
what is the equation of the vertical asymptote(s)?

Answer 1

vertical asymptote at \(x=-5\) where the denominator is zero
domain is all real numbers except \(x=-5\)
graph looks like this

Answer 2

thank you wha eould the horizontal asymptote be ?

Answer 3

wouldnt it be 9

Answer 4

there is no horizontal asymptote since the degree of the numerator is larger than the degree of the denominator

Answer 5

you can also see it from the graph

Answer 6

ok thank you so much
