Part I: Domain and Range-identify the domain and range of each graph. Problem / Work Answe 2+ 6+ 2+ 1. Week 15 Homework Packet p

vampirchik [111]

Domain is the set of input values,

In the graph x axis show the domain

Where the x values is lies at -2,-1,0,1,2

Sothe domain will be :

$\text{Domain =-2}\leq x\leq2$

Range is the set of output values,

In the graph the value of function at y axis is : 0,2,4,6,8-2,-4.....

So, the range will be :

$\text{Range = -}\infty\leq y\leq\infty$

Which of the following functions best fits the data shown in the scatterplot below? y=100x+2y is equal to 100 x plus 2 y=20x2+10

KengaRu [80]

The equation of the scatter plot is (a) y = 100x + 2

<h3>How to determine the equation of the scatterplot?</h3>

The line of best fit of the scatter plot passes through the points

(x,y) = (0,2) and (1,102)

Start by calculating the slope using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{102 - 2}{1 - 0}$

m = 100

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = 100(x -0) + 2

Evaluate

y = 100x + 2

Hence, the equation of the scatter plot is (a) y = 100x + 2
