Answer 1

Are you comfortable with what the domain actually is?

Answer 2

yes. you explained that before

Answer 3

\[\large f(x)=\frac{ \sqrt{x+6} }{ (x+7)(x-9) }\]

Answer 4

remember the standard square root function, y=sqrt(x) how x has to be 0 or larger to get a value

Answer 5

so for the root function, you want the stuff underneath to be greater or equal to zero to get a real number back... here it is (x+6) underneath... what does that tell ya

Answer 6

@helpppp is it x>0?

Answer 7

Gimme a sec to figure it out

Answer 8

thanks!

Answer 9

Okay, so to find the domain you need to find where the expression is defined. In your case x is going to be greater than or equal to -6. Therefore, your domain will be \[[-6,\infty)\].

Answer 10

B. X is greater than or equal to -6, remember?

Answer 11

Don't forget to find values that make the denominator zero...

Answer 12

My brain is dead rn.... >.<

Answer 13

mine too... :-( I'm trying though

Answer 14

x ≥ -6, x ≠ 9 yes
