Transformations Quadratic Functions

Write the equation of the quadratic function. (parabola)

• y = x² - 5

• y = x² + 5

• y = ( x - 5 )²

• y = ( x + 5 )²

Given f(x) = (x + 6)² - 2 , how did we transform from the parent function?

• Horizontal shift left 6, vertical shift up 2

• Horizontal shift left 6, vertical shift down 2

• Horizontal shift right 6, vertical shift down 2

• Horizontal shift right 6, vertical shift up 2
