Because this is a sideways-opening parabola, and to the right to be specific, it will occupy Quadrants I and IV only. The vertex is at (3, 0).
Answer: < -4/5, 3/5>
This is equivalent to writing < -0.8, 0.6 >
======================================================
Explanation:
Draw an xy grid and plot the point (-4,3) on it. Draw a segment from the origin to this point. Then draw a vertical line until reaching the x axis. See the diagram below.
We have a right triangle with legs of 4 and 3. The hypotenuse is through use of the pythagorean theorem.
We have a 3-4-5 right triangle.
Therefore, the vector is 5 units long. This is the magnitude of the vector.
Divide each component by the magnitude so that the resulting vector is a unit vector pointing in this same direction.
Therefore, we go from < -4, 3 > to < -4/5, 3/5 >
This is equivalent to < -0.8, 0.6 > since -4/5 = -0.8 and 3/5 = 0.6
Side note: Unit vectors are useful in computer graphics.
A ratio is usually a fraction and an equation is a group of numbers set out to find an answer
Answer:
The domain of a relation is the set of all the x-terms of the relation.
If an x-term appears twice in a relation, only list in once in the domain
The x-values for those three ordered pairs are 2, -2, and -2. For the first ordered pair, you move two positive units along the x-axis, and then along the y-axis to -11. For the second ordered pair, you first move two negative units on the x-axis to -2, and then 11 positive units on the y-axis
