Considering the equation of the parabola, the directrix is: x = 1.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of an horizontal parabola, of vertex (h,k), is given by:
(y - k)² = 4p(x - h).
The directrix is at x = h - p.
For this problem, the equation is:
(y + 3)² = 8(x - 3).
The relevant coefficients for this problem are:
4p = 8 -> p = 2, h = 3.
Hence the directrix is:
x = h - p = 3 - 2 = 1.

Answer:
2.63905733
Step-by-step explanation:
Sorry I didn't round it
Formula
The answer is -6.
First you need to balance, so add 4 to both sides.
2 = -x - 4
Now you need to divide both sides by -1.
6 = -x
Boom.
-6 = x
Answer:
degree 1
Step-by-step explanation:
The trapezoidal rule is exact when the second derivative is zero. This occurs when the polynomial is degree one or less
