Hey there!!
Okay so let's start simplifying this :D
-| -2 + 9| <---- remember that the "vertical bars" are absolute value signs
Absolute value signs will make any values within them into a positive value even if it was negative in the first place
-| 7 | <---- first simplify what is within the absolute value signs
<u>- 7</u><u /> <----- this is your final answer!!!
I hope this helps you! ^__^
Answer:
6:24
1:4
2:8
Step-by-step explanation:
Simplified all the way is 1:4 so just make sure that you multiply the same number by both the numerator and the denominator
The rang of an inverse function is the domain of the normal function
So you just gotta find the domain of that which is x is greater than or equal to 0
