Find any points of discontinuity for y = 5x+6/x2+6x+9

x = -3 is the point of discontinuity.

Hence, option B is correct.

Step-by-step explanation:

Given the expression

In order to determine the discontinuity, the denominator must be 0.

so let us solve the denominator to get the values of x

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

Subtract 3 from both sides

Therefore, x = -3 is the point of discontinuity.

Hence, option B is correct.

x=6 and x=3
