Answer:

Step-by-step explanation:

This is written in the standard form of a quadratic function:

where:
- ax² → quadratic term
- bx → linear term
- c → constant
You need to convert this to vertex form:

where:
To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:

Using your original equation, identify the a, b, and c terms:

Insert the known values into the equation:

Simplify. Two negatives make a positive:

X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:

Simplify using PEMDAS:

The value of y is -6 (3,-6). Insert these values into the vertex form:

Insert the value of a and simplify:

Answer:
A U B = {17, 19, 20, 21, 22, 24}
Step-by-step explanation:
The symbol U is the union symbol, which denotes the union of two sets.
This means that given two sets A and B, the expression
A U B
indicates all the elements that belong to either set A or set B.
In this problem, we have the following two sets:
A = {19, 20, 21, 24}
B = {17, 19, 20, 22}
We can therefore list all the elements belonging to either set A or set B, they are:
17, 19, 20, 21, 22, 24
So, the expression A U B indicates the set:
A U B = {17, 19, 20, 21, 22, 24}
