8/16- Warmup

Match the equation to its description.

• Stretched by 2 and up 4
• Compressed by 2 and up 4
• Stretched by 2 and left 4
• Compressed by 2 and left 4

Describe the transformation from the parent function to h(x).

How would you describe the transformation from the parent function to g(x)?

• vertical stretch by a factor of 2

• horizontal stretch by a factor of 2

• vertical translation 4 units down

• horizontal translation 5 units left

Which equation below is a quadratic function translated up 5 units?

• y = x² + 5
• y = (x + 5)²
• y = 5x²
• y = -x² - 5

Select all the equations that show a vertical shift from its parent function.

•  $y=\left|x+1\right|$  

•  $y=x^3+4$  

•  $y=x-10$  

•  $y=\left(x-3\right)^2$  

•  $y=x^2-1$  

Select all equations that show a horizontal shift from its parent function.

•  $y=\left|x-4\right|$  

•  $y=\left(x-9\right)^3$  

•  $y=x^2+8$  

•  $y=\left|x\right|-5$  

•  $y=\sqrt{x}+1$  

How did we transform from f(x) =x² 
to
g(x) = -3x²

• reflection in x-axis and vertical shift down
• reflection x-axis and vertical stretch
• horizontal stretch
• reflection x-axis and vertical compression

In the equation f(x)=5(x+3)²-10 what does the 5 do?

• Vertical stretch by 5
• Horizontal compress by 5
• Reflect
• Move up 5
