The only order pairs among the given options that represent a function is :
- (9 , -3) , (9 , -1) , (9 , -1)
Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
The variables are the letters g and h because, t<span>he coefficient is the number in front of the variables (the letters are variables)</span>

Step-by-step explanation:
Answer:
The algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.
Step-by-step explanation:
Different ways to present algebraic expressions without changing their meaning:
1. We can describe the algebraic expressions in words so that its meaning remains same.
For example : 3x+y = Sum of 3 times of an unknown variables x and y.
2. We can describe the algebraic expressions in equivalent expressions, so that its meaning remains same.
For example : 6x+3y = 3(2x+y)
Therefore, the algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.
