The point that is not included in the solution set for the inequality in the graph is (-1, 3).
<h3>How to explain the graph?</h3>In the information given, (h, k) is the vertex point. In the graph, the vertex point will be (1, 2). The equation will be:
y = a(x + 1)² + 2
By the point of the graph(0, 3) the value of a will be:
3 = a(0 - 1)² + 2
3 = a + 2
a = 3 - 2
a = 1
The equation this becomes:
y = 1(x - 1)² + 2.
y = x² - 2x + 1 + 2
y = x² - 2x + 3
Therefore, the point that is not included in the solution set for the inequality is (-1, 3).

Answer:
Which expression is equal to ?
The correct answer is B.
Step-by-step explanation:
Inside of the radical you have . If you find the cube root of that, you get 4a^2. Go ahead and write that outside of the parenthesis:
If you re-write what is inside of the radical, you get:
Basically I expanded what was inside of the radical so I could find the cube roots of b^7 and c^9.
Now, take the cube root of b^7:
Notice how I could only factor out the two "b^3" that were inside the radical symbol, and how I left the b^1 inside the radical symbol because I couldn't factor it out.
Let's now get the cube root of c^9. Since it's a perfect cube, there won't be any "c"s left inside of the radical symbol:
