Step 1

Find the y-intercepts.

Step 1.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 1.2

Using the slope-intercept form, find the y-intercept for $f (x) = 1$ .

$b_{1} = 1$

Step 1.3

Using the slope-intercept form, find the y-intercept for $g (x) = 1$ .

$b_{2} = 1$

Step 1.4

List the y-intercepts.

$b_{1} = 1$

$b_{2} = 1$

$b_{1} = 1$

$b_{2} = 1$

Step 2

The vertical shift depends on the y-intercept value $b$ , where $b = b_{2} - b_{1}$

$b_{2} - b_{1} = 0$

Step 3

Since $b = 0$ , the graph is not shifted.

Not Shifted

Find the slopes.

Step 4.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 4.2

Using the slope-intercept form, find the slope for $f (x) = 1$ .

$m_{1} = 0$

Step 4.3

Using the slope-intercept form, find the slope for $g (x) = 1$ .

$m_{2} = 0$

Step 4.4

List the slopes.

$m_{1} = 0$

$m_{2} = 0$

$m_{1} = 0$

$m_{2} = 0$

Step 5

The vertical stretch depends on the slope.

If $| m_{2} | < | m_{1} |$ , vertical compression

If $| m_{2} | > | m_{1} |$ , vertical stretch

If $| m_{2} | = | m_{1} |$ , no vertical stretch or compression.

Step 6

Since $| m_{2} | = | m_{1} |$ , there is no vertical stretch or compression.

No vertical stretch or compression

Step 7

Since $m_{1}$ and $m_{2}$ do not have opposite signs, the graph is not reflected about the y-axis.

Not reflected about the y-axis

Step 8

Describe the transformation from the function $f (x) = 1$ .

No transformation
