Write the equation of the line that is two times less steep from the equation y=x.

y = ______

Describe the transformation of y = f(x) for the new function
 y = 1/5f(x)

• The graph of y = f(x) compressed horizontally by a factor of 1/5
• The graph of y = f(x) was stretched horizontally by a factor of 5
• The graph of y = f(x) was compressed vertically by a factor of 1/5
• The graph of y = f(x) was stretched vertically by a factor of 5

 $f\left(x\right)=2x+3$  
 $g\left(x\right)=2x-4$  

Rewrite g(x) in translation form:  $g\left(x\right)=f\left(x\right)+k$  

Do NOT type spaces in your answer.

What is the correct description of the transformed function 

 $y=f\left(x+4\right)-10$  ? 

• Horizontal shift of 4 to the right, reflection, dilation of 10

• Horizontal shift of 4 to the right, vertical shift down 10

• Horizontal shift of 4 to the left, vertical shift up 10

• Horizontal shift of 4 to the left, vertical shift down 10

Given f(x) = 7x +3.  Translate the function up 6 and write the new rule.

• g(x) = 7x +9
• g(x) = 7x -3
• g(x)= 21x+6
• g(x) = 2x +3

When translating an object which direction would you apply to the "x" coordinate?

• left or right

• Up or down
