## orbie 3 years ago I need a refresher on how to do this. Unfortunately I don't have my notes with me. Problem is attached.

Ok for starters g(2) means solve the equation when x=2 So which equation would you use when x=2?

3. swissgirl

@orbie R u there?

4. orbie

No idea is like asking that if you plug 2 into the left side of the equation, it must equal whatever is on the right side of the equation? =/

5. swissgirl

well if you look at G(x) it gives you 4 equations and after each equation it says when you should use each equation. The first equation should be used when x is less than or equal to 1 The second equation should be used when x is less than 1 and when x is less than or equal to 3 which basically only includes 2 and 3 The third equation is when x is inbtwn 3 and 6 but not including 3 or 6 so this basically means when x equals 4 or 5 you use the third equation The last equation is used when x is equla to 6 or greater than 6 So which equation would we use when x=2?

6. orbie

the second equation $\left| x-12 \right|$

7. swissgirl

correct So g(2) means we replace our x with 2 g(2)=|2-12| g(2)=|-10|=10 So g(2)=10

ooooh okay I understand now. Thank you!
