Question

Find the indicated one sided limits of f.

f(x)= (x^2+8)/(x^2-25)

what is the limit as x goes to -5+(from the right side)?

What is the limit as x goes to 5+(from the right side?

Answer 1

if x = -4.99
f = -329
if x = -4.999
f = -3299
negative infinity
numerator --> 33
denominator ---> - 0 because x^2 always < 25

opposite for x>5 by a little
---> + oo
