<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
The distance formula for two points on a number is | a-b |, that is the absolute value of a - b. In this case a = 137.5 and b = -62.5, with these numbers in mind we can make substitute for a and b and solve, | 137.5 - -62.5 | = n. Since when there are two negative signs present they turn positive, we can see that the distance between point a and point b and therefore the distance between the two elevators in 200 feet.
| 137.5 - -62.5 | = n
| 137.5 + 62.5 | = 200
