Given:
The quadratic equation is
To find:
The x-coordinate and y-coordinate of the vertex.
Solution:
If a quadratic function is defined by , then the vertex is defined as:
If , then the function has a maximum at the vertex and ff , then the function has a minimum at the vertex.
We have,
Here, .
Since , therefore the function has a minimum at the vertex. So, fill min in first blank.
Now,
Putting x=3 in the given function, we get
Therefore, the vertex is at point (3,-12).
Answer:
D
Step-by-step explanation:
The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).
<2 + 40 + 40 = 180 Combine the left
<2 + 80 = 180 Subtract 80 from both sides
<2 = 180 - 80
<2 = 100 degrees.
That's not the answer. We have to solve for x
<2 = x + 106
100 = x + 106 Subtract 106 from both sides
100 - 106 = x
x = - 6
