Question

What is the equation for the vertical asymptote of the function shown below?


f(x)=5x⁴-7/(x+3)

a.x=3
b.x=5
c.x=7/3
d.x=-3

Answer 1

d.x=-3

Answer 2

Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. (They can also arise in other contexts, such as logarithms, but you'll almost certainly first encounter asymptotes in the context of rationals.)
