Answer:
4
Step-by-step explanation:
Simplify the given expression by doing each operation as per the order of operations. The order of operations is a systematic way of tackling an equation, that ensures that the result attained will be true when one solves the equation; remember, the order of operations states;
1. Parenthesis
2. Exponents
3. Multiplication/ Division
4. Addition/ Subtraction
Simplify the equation by combining terms as per the order of operations;
[ ( 4 + 8 ) * 3 ] / 9
= [ 12 * 3 ] / 9
= 36 / 9
= 4
The parent function for quadratic equations is as followed:

where a for vertical stretches, b is for horizontal stretches, h is the x value of the vertex, and k is the y value of the vertex.
The vertex of the is (-3, -2), so we can write the first part of the equation:

To determine if the graph has any stretches, we can check how changes to the x coordinate affect the y value. If there are no stretches, as the x coordinate moves away from the vertex, the y coordinate should be x^2 from the vertex. If we test with a couple points on the graph, wee see that this is true, so there are no stretches. The answer is:
