What are the discontinuity and zero of the function f(x)= x^2 + 5x + 6/ x+2 - Discontinuity at (-2, 1), zero at (3, 0)

- Discontinuity at (-2, 1), zero at (-3, 0)

-Discontinuity at (2, 5), zero at (3, 0)

-Discontinuity at (2, 5), zero at (-3, 0)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
