Answer:

-2 and -4

Step-by-step explanation:

Given the function f(x) = x² + 6x + 8

If f(x) = 0

x² + 6x + 8 = 0

Factorize

x² + 4x + 2x+ 8 = 0

x(x+4)+2(x+4) = 0

(x+2)(x+4) = 0

x+2 = 0 and x+4 = 0

x = -2 and -4

Hence the zero of the function is -2 and -4

Answer:

vertical asymptote at x = 7

horizontal asymptote at y = 6

Step-by-step explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote.


solve:  

x − 7 = 0 ⇒ x = 7  is the asymptote

Horizontal asymptotes occur as

lim ,f(x)→ c(a constant)

x → ± ∞

divide terms on numerator/denominator by x

f ( x ) = 5/ x +6= 5 /x + 6

x/ x − 7 /x      1 − 7/ x

as   x ± ∞ , f ( x ) → 0 +6

                1 − 0

⇒ y = 6  is the asymptote

graph{((5)/(x-7))+6 [-20, 20, -10, 10]}
