Question
For the function $ f $ whose graph is shown, state the following.(a) $ \displaystyle \lim_{x\to -7}f(x) $(b) $ \displaystyle \lim_{x\to -3}f(x) $(c) $ \displaystyle \lim_{x\to 0}f(x) $(d) $ \displaystyle \lim_{x\to 6^-}f(x) $(e) $ \displaystyle \lim_{x\to 6^+}f(x) $(f) The equations of the vertical asymptotes.
Step 1
Looking at the graph, we see that as we approach -7 from the right, the function is going to negative infinity. Since there is no function value from the left of -7, we can say that $\lim _{x \rightarrow-7} f(x)=-\infty$. Show more…
