Let f(x) = x2 – 7x + 10
for x² + 25
r2 - 25
A, for x = 5
B. for x = -5
(a) Are the lines x = 5 and x = -5 vertical asymptotes of
f? Justify your answer.
(b) Identify all horizontal asymptotes of f. Justify your
answer.
(c) Is there a value of A that makes f continuous at x = 5?
(d) Is there a value of B that makes f continuous at
x = -5?
