The correct answer is 3, it is irrational and equal to 5\sqrt{2}.

The first step is to figure out the answer, then we can deduct whether it is rational or not, giving us our answer. To solve this, we first need to simplify \sqrt{32}. \sqrt{32} is equal to \sqrt{2 * 2 * 2 * 2 * 2}, which is equal to 4\sqrt{2}. Now our expression is 4\sqrt{2} + \sqrt{2}. This simplifies to 5\sqrt{2}. Since this expression has a square root, it is irrational, and since the result is 5\sqrt{2}, the answer is 3).

Given:

The set of pair and graphs.

To find:

The domain and range.

Solution:

We know that,

Domain is the set of x-values or input values.

Range is the set of y-values or output values.

(a)

The given set of ordered pairs is

{(-3,3),(5,5),(-3,2),(5,3)}

Here, the x-coordinates are -3, 5, -3, 5.

A set contains distinct values.

Therefore, the domain is {-3,5}.

(b)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}

Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.

Therefore, the range is {0, 0.5, 1, 2, 3}.

(c)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,3),(-1,3),(0,1),(2,4)}

Here, the x-values are -2, -1,0, 2.

Therefore, the domain is {-2,-1,0,2}.

Answer:

5/8

Step-by-step explanation:

To find the slope, use the formula

m = (y2-y1)/(x2-x1)

   = (2 - -3)/(6 - -2)

   = (2+3)/(6+2)

   = 5/8
