Answer:
The range is the output.
Step-by-step explanation:
A function consists of two parts:
1. Domain - Domain is the set of all values that are inputted to a function. So, domain is set of all possible values of
.
2. Range - It is the set of all output values for given input values. It is the set of all possible values of
for given
values.
Therefore, range is the output to a function.
The precent of increase is 20%
-2(2x+9)>-4x+9
1)We solve this inequation:
-2(2x+9)>-4x+9
-4x-18>-4x+9
-4x+4x-18>9
-18>9 This is not true, because -18<9; Therefore this inequation is never true.
Answer: this inequation is never true.
Answer:

Step-by-step explanation:
