Answer:
(4, -25)
Step-by-step explanation:
In this case, the quadratic formula is in the form:
ax² + bx + c
Since they also give you the formula for the vertex, you just need to plug the values in.
The x coordinate in the vertex is 8/2(1), or 4.
You take the x = 4 and plug it into your quadratic equation.
f(4) = 16 - 32 -9
= -25
The vertex is (4, f(4)) or (4, -25)
I hope this helps!
A graph of a non-vertical straight line is a linear function.
What is diameter:
in geometry, a <u><em>diameter</em></u> of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.
What is radius:
In classical geometry, a <u><em>radius</em></u> of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
Explanation:
The <u><em>diameter </em></u>is the line that goes across the center of the circle and double the <u><em>radius</em></u> which is half, therefore <u><em>KR</em></u> is the <u><em>correct answer.</em></u>
Answer:
<u><em>KR, D, or the last option.</em></u>
Statement answer:
<u><em>Segment KR is the Diameter of Q.</em></u>

Answer:
B) All the real numbers except 4.
Step-by-step explanation:
The given rational expression f(x) = 
To find the domain of the rational function, first we have to find the restricted domain.
To find the restricted domain set the denominator equal to zero.
4 - x = 0
x = 4
The restricted domain is at x = 4.
Which means the function does not exist when x = 4. When we plug in x =4 in the rational function, we get the denominator is 0.
Therefore, the function does not exist at x =- 4.
This means except 4 all the real numbers are the domain.
Hope this will help you to understand the concept.
Answer: B) All the real numbers except 4.
Thank you.
