Functions can't have multiple y values have the same x value.

[(-5, 1), (-3, 2), (-1, 3) (1, 4), (3, 5)] ** No repeating x-values.

[(-2, 1), (-4, 2), (0,3), (4, 1), (-2,5)]

[(-1, 5), (-1,4), (-1, 3), (-1, 2) (-1, 1)]

[(-6, -4), (-4, -2), (0, 0), (-4, 2) (-6, 4)]

Answer:

[(-5, 1), (-3, 2), (-1, 3) (1, 4), (3, 5)]

What is the perimeter of a square that has an area of 100?

nikdorinn [45]

Answer:

The perimeter would be 40.

Step-by-step explanation:

A square would have all the sides equal. So, to find what times what equals 100 that are the same numbers, we can simply do root 100.

The square root of 100 is 10. So, each side of the square is 10 units. A square has has 4 equal sides. So, 10 + 10 + 10+ 10 = 40.

40 is the perimeter.

How does the graph of y = a(x – h)2 + k change if the value of h is doubled? The vertex of the graph moves to a point twice as f

KIM [24]

Answer:

The vertex of the graph moves to a point twice as far from the y-axis.

Step-by-step explanation:

How does the graph of y = a(x – h)2 + k change if the value of h is doubled?

The vertex of the graph moves to a point twice as far from the x-axis.

<h2>The vertex of the graph moves to a point twice as far from the y-axis. </h2>

<em>because the role of h is to indicate the distance of the vertex from the y-axis.</em>

The vertex of the graph moves to a point half as far from the x-axis.

The vertex of the graph moves to a point half as far from the y-axis.

Construct a confidence interval of the population proportion at the given level of confidence. x = 125, n = 250, 90 % confidence

madam [21]

Answer: 90% confidence interval would be (0.448, 0.552).

Step-by-step explanation:

Since we have given that

x = 125

n = 250

So, $\hat{p}=\dfrac{x}{n}=\dfrac{125}{250}=0.5$

We need to find the 90% confidence interval.

so, z = 1.64

So, interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.5\pm 1.64\sqrt{\dfrac{0.5\times 0.5}{250}}\\\\=0.5\pm 0.0519\\\\=(0.5-0.0519,0.5+0.0519)\\\\=(0.448,0.552)$

Hence, 90% confidence interval would be (0.448, 0.552)
