Transformations and Quadratics Review

Which transformation transforms the graph of
f(x) = x² to the graph of
g(x) = (x + 4)²?

• a vertical translation 4 units up
• a vertical translation 4 units down
• a horizontal translation 4 units to the left
• a horizontal translation 4 units to the right

How did we transform from f(x) =x²

to

g(x) = -3x²

• reflection over x-axis and vertical shift down 3

• reflection over x-axis and vertical stretch by 3

• horizontal stretch by 3

• reflection over x-axis and vertical compression by -3

Match the description to its equation.

How did we transform from the parent function?

g(x) = -1/5(x - 1)² + 7

• reflection over x-axis, vertical compression by 1/5, right 1, up 7

• vertical compression by -1/5, left 1, up 7

• reflection over x-axis, right 1, down 7

• reflection over the x-axis, vertical stretch by 1/5, right 1, up 7
