What is the directrix of the following graph? X = -3 Y= 3 Y = -3 X = 3

Mathematics

Answer:

y = 3

Step-by-step explanation:

The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.

So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)

Now, we have to get the value of a since the equation id the directrix is y = 4 - a.

Now, the parabola passes through the point (3,5) {Obtained from the graph).

Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1

Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)

Organize the following polynomial expressions from least to greatest based on their degree: x 2xyz 9x3y2 18x2 5ab − 6y 4x4 3x2 −
Advocard [28]

The order will be IV, III, I, and II.

<h2>Polynomial</h2>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

 I.  x + 2xyz

II.  9x³y²

III.  18x² + 5ab - 6y

IV. 4\rm x^{4} + 3x² - x - 4

<h3>To find </h3>

The polynomial expressions from least to greatest are based on their degree.

<h3>How to organize?</h3>

4\rm x^{4} + 3x² - x - 4 is a biquadratic ploynolmial.

18x² + 5ab - 6y is a cubic polynomial.

x + 2xyz is a quadratic polynomial.

9x³y² is a monomial polynomial.

So the order will be IV, III, I, and II.

More about the polynomial link is given below.
