3) Graph by making a table. y=x

Zanzabum

Answer:

See attachment for graph

Step-by-step explanation:

Given

$y = x$

Required

Plot the graph

First, we need to make a table.

To do this, we assume values for x

When $x = 1$

$y = x = 1$

$(x_1,y_1) = (1,1)$

When $x = 2$

$y = x = 2$

$(x_2,y_2) = (2,2)$

When $x = 3$

$y = x = 3$

$(x_3,y_3) = (3,3)$

When $x = 4$

$y = x = 4$

$(x_4,y_4) = (4,4)$

So, the table is:

$x || 1 || 2 || 3 || 4$

$y || 1 || 2 || 3 || 4$

kaheart [24]

Answer: 40,320

Step-by-step explanation:

By Permutation,

The number of arrangements for n things is given by n!.

[Here order matters]

Given: Number of people will give a presentation in class =8

Then, the number of different orders = 8!

= 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 40320

Hence, the number of different orders = 40,320
