Graph each absolute value function. State the domain, range, and y-intercept.
Paraphin [41]

Answer:

i)D:x\in R

ii)R: y\ge-3

iii) Y-int:(0,-1)

Step-by-step explanation:

i) The given absolute value function is;

f(x)=|x+2|-3.

The absolute value function is defined for all real values of x.

The domain is all real numbers.

ii) The range is all y-values that will make x defined.

The given function,

f(x)=|x+2|-3.

has vertex at, (-2,-3) and opens upwards.

This implies that, the minimum y-value is -3.

The range is y\ge-3

iii) To find the y-intercept substitute x=0 in to the function.

f(0)=|0+2|-3.

f(0)=|2|-3.

f(0)=2-3.

f(0)=-1.

The y-intercept is (0,-1)

Answer:

  y = 6x +1

Step-by-step explanation:

To write the slope-intercept form equation for a line, you need to know the slope and the y-intercept. These can be found from their respective formulas.

__

<h3>slope</h3>

The slope of a line between points (x1, y1) and (x2, y2) is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

For points (-1, -5) and (0, 1), the slope is ...

  m = (1 -(-5))/(0 -(-1)) = 6/1

  m = 6

<h3>y-intercept</h3>

The y-intercept is the value of y where the line crosses the y-axis. That axis is where x = 0. There is a formula that can be used to find the y-intercept from the slope and a point on the line:

  b = y -mx . . . . . y-intercept of line with slope m through point (x, y)

However, one of the given points is already the y-intercept: (0, 1). It tells you b=1.

<h3>equation</h3>

The slope-intercept equation is ...

  y = mx +b

  y = 6x +1

Create the pattern with the rule n×2+1.
Yuki888 [10]

Answer:

3,5,7,9,11

Step-by-step explanation:

You would put the whole numbers in order as n and solve

1. 1*2+1 = 3

2. 2*2+1 = 5

3. 3*2+1 = 7

4. 4*2+1 = 9

5. 5*2+1 = 11

You would notice that the numbers are odd numbers in order
