Please solve Question 8. 8. Give an e-s proof that Lim-> -4. 3(3x^2+20x+39)/(x^2+8x+19)=7Please also use the hints for question 8. You can see that on the right side. Please demonstrate clear proof that's readable. Please be clear.

2. Exercise 3, page 176 of the text. 3. Exercise 9, page 177 of the text. 8. Hints: First convert f(r) - L to the form g(x) (x+4). On the interval 4. Exercise 11, page 177 of the text. [-5, -3) I obtain My = 14 as an upper bound for the numerator of g(x), and My - 3 as a lower bound for the denominator As 5. Let S be the upper-half plane of R? with the r,-axis not included a consequence, in Theorem 16.10 we can use M - 14. For 6 := What are the limit points of S? min (1, 314] we therefore have If (x) - 7)
