<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:
(1,1)
Step-by-step explanation:
Graph: y = -x^2 + 2x
Answer: 2 - 4x = 6
Please mark me as brainliest
Answer:
y=3x-2
Step-by-step explanation:
The formula for slope is y=mx=b
You can find the slope by finding two points that lie on the line (1,1) & (0,-2)
The formula for slope is 
You plug the values in and you get 
Simplify and you get 3
The slope is 3
The y-intercept (b) is -2
There is a type of ammo in f/o/r/t/n/i/t/e that can be magically used for every single gun. You open an ammo box, and out pops 141 rounds of that ammo. You have already collected 6 guns. How many rounds go into each gun?
The answer is 23.5
THERE IS A REMAINDER??
Nothing happens! Literally! It never happened! There is no ammo that can be used for all the guns. GG and hope to see you on the game sometime, cause...i am not allowed to have it.
