What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and k = - 4 and a = 1
Vertex (a, k) so it is (1,-4)
Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)
Answer:h=f(X)-x-k
Step-by-step explanation:
F(x)=x+ h+k
h = F(x)-x -k
1) 5 + ( 2 + 7) = (5 + 2) + 7
It is the associative property of the addition.
This property states that when adding 3 numbers, the grouping or association of the numbers does not change the result.
2) <span>The second expression is unreabable
</span>
<span>3) h + 0 = h
</span>
<span>It is the identity property.
</span>
This property states that 0 is the identity element of the addition and any number added to it is equal to the same number.
AS you know, 5 + 0 = 5, 1234 + 0 = 1234; 0 + 2548 = 2548.
Answer:
If there is a 105 try that one. It makes since that it's 105 or 75.
