+360 Its a rational expressions problem.
What are the domain restrictions of the expression h^2+3h−10
_________
h^2−12h+20 ?
Select each correct answer.
h≠−10
h≠−2
h≠10
h≠2
h≠−5
h≠5
Please and thank you! 0^>
Also, hope you are all having a good morning. Its chilly out! I'm not a cold weather person, shame on me.
+37146 The DENOMINATOR cannot equal ZERO
The denominator factors to (h-2)(h-10) so h (or x) cannot equal 2 or 10....all other values of h (or x) are allowed.
+129852 We have a "rational" function here, Phoenix [ a ratio of functions ]
The domain restrictions are the values of h that makes the denominator = 0
So
h^2 - 12h + 20 = 0 factor
(h - 10) ( h - 2) = 0
Set each factor to 0
h - 10 = 0 h - 2 = 0
h = 10 h = 2
So....h = 2 , h =10 are the domain restrictions
HAHAHA!!!!!. I live in Louisiana.....after our brutal Summers, a bit of cold weather is welcome....but......not too cold!!!
+360 Thanks CPhill! Yes, let's hope the weather does not get much colder!!! At least you get a break from Louisiana sun.
It's going to be a freezing Oregon winter here lol.
