Quadratic Transformations Vocabulary

If the blue is f(x)=x^2, then the red must be..

(Move from blue to red. Just like we did in khanacademy yesterday)

• g(x)=x² - 5

• g(x)=x² + 5

• g(x)=(x - 5)²

• g(x)=(x + 5)²

Compared to the parent function, f(x) = x², which of the following is the equation of the function after a vertical stretch by a factor of 3? Hint: Look at notes! Is 'a' supposed to be inside or outside of parenthesis???

• A

• B

• C

• D

Compared to the parent function, f(x) = x², which of the following is the equation of the function after a vertical compression by a factor of 1/3? Hint: Look at notes! Is 'a' supposed to be inside or outside of parenthesis???

• A

• B

• C

• D

Compared to the parent function, f(x) = x², which of the following is the equation of the function after a horizontal shift to the right 7?

• A

• B

• C

• D

Compared to the parent function, f(x) = x², which of the following is the equation of the function after a horizontal shift to the left 2?

• A

• B

• C

• D

You move from blue to red. Just like Khanacademy

• g(x)=2x²

• g(x)=0.5x²

• g(x)=x²+2

• g(x)=(x+2)²

What is the green dashed line called?

• roots or x-intercepts

• parabola

• axis of symmetry

• vertex

What are the transformations? y=(x-2)²+4 (Choose ALL that apply.)

• Horz shift right 2

• Horz shift left 2

• Vert shift up 4

• Vert shift down 4

Match the equation to its description.

• Vertical Stretched by 2 and translation up 4

•  Vertical Compressed by 2 and translation up 4

• Horizontal Stretched by 2 and translation left 4

• Horizontal Compressed by 2 and translation right 4

In the vertex form f(x) = a(x - h)² + k , what does the 'k' value do?

• Shifts the function left or right

• Reflects over the x-axis

• Vertical stretch or compression

• Shifts the function up or down
