Question

Someone help me with this! A friend of mine distracted me with my class and now I don’t understand this part! It’s evaluating functions btw

Answer 1

I'll focus on the parts circled in red.

We have this function
`\text{r}(\text{x}) = \frac{\text{x}+13}{\text{x}-3}`

Question 6 asks what value of x is not allowed. That would be 3 since it causes the denominator to turn into zero. Dividing by zero is not allowed.

`\text{x}-3= 3-3 = 0`

So we must kick
`\text{x} = 3` out of the domain. Any other value of x is allowed.

Final Answer: 3
