What is the first step for solving this problem: 12÷ 6(3)+8

Division.

Step-by-step explanation:

There are two rules that you follow. One is PEMDAS, and the other is the     left -> right rule.

Note that PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

The order of operation is: P , (E & R) , (M & D) , (A & S), parenthesis meaning they can be interchangeable, due to the left -> right rule.

Solve:

First, divide:

12/6 = 2

Next, multiply:

2 x 3 = 6

Finally, add:

6 + 8 = 14

14 is the answer.

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
