Question 987938: Explain why the function is discontinuous at the given number a . sketch the graph of the function
f(x)=(1)/(x+2)
a=-2
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
f(x)=(1)/(x+2)
a=-2
x=-2
f(-2) is undefined for your function, so no point at x=-2. Instead, sign changes around x=-2, leading to vertical asymptote at x=-2.
