Iam not good at math!
given the function f(x)= \frac{x^2+7x+10}{x^2+9x+20} describe where the function has a hole and how you found your answer.

Only hole of function is at x=(-4)

Step-by-step explanation:

Given the function is

In order to find holes of any function, you should find when function is becoming undefined or say " infinity"

Given function is polynomial function.

It will become undefined become denominator become zero

Solving for x value when denominator become zero

we get possible holes at x=(-4) and x=(-5)

Check whether you can eliminate any holes

Now, Solving for x value when numerator become zero

x=(-5) and x=(-2)

x=(-5) is common is both numerator and denominator.

So that, we can eliminate it.

Therefore, Only hole of function is at x=(-4)

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
