<h2>Range of a Quadratic Function</h2>
The range tells us the possible <em>y</em>-values that occur in the function.
When describing the range, we can write an inequality using <em>y</em>.
When describing the range of a quadratic function, we typically use the ≥ or ≤ symbols when writing the inequality.
To write the range of a quadratic function,
- Find the vertex
- Determine whether the parabola opens up or down
- Set <em>y</em> ≥ or ≤ the y-coordinate of the vertex
<h2>Solving the Question</h2>
We're given:
- Vertex at (0,4)
- Other points on the graph: (-2,0), (-1,3), (1,3), (2,0)
Because we're directly given the vertex, we just have to determine now whether the parabola opens up or down.
- If the other points on the graph always have a lower <em>y-</em>coordinate value, then the graph opens down
- If the other points on the graph always have a greater <em>y-</em>coordinate value, then the graph opens up
The other points that fall on the graph that we're given all have a lower y-coordinate value than 4, that means this parabola opens down.
Therefore, all other y-values for the function will be less than 4.
Therefore, y ≤ 4.
<h2>Answer</h2>
y ≤ 4

Answer:
Probability = 1/8.
Step-by-step explanation:
A number cube has six sides. Each side has a number from 1 to 6. This means that there are 3 even numbers (2, 4, and 6) and 3 odd numbers (1, 3, and 5). Therefore:
P(number cube lands on an even number after roll) = Number of even numbers/Number of total numbers. = 3/6 = 1/2.
Since the cube has to be rolled three times, the probability will be multiplied 3 times (assuming that each roll in independent of each other). Therefore:
P(number cube lands on an even number 3 times after roll) = 1/2 * 1/2 * 1/2 = 1/8.
Therefore, the answer is 1/8!!!
Answer:
Slope form of line y = 4x +41
Step-by-step explanation:
m= 4
The y-intercept of the line that passes through the given point (-9,5) is
5 = 4(-9) + b
b= 5 +36
b=41
The equation of the line that passes through the given point (-9,5) is
y =mx +b
y = 4x +41
