Shifts and Transformations of Quadratics

Write the equation of this transformation: reflection across x-axis, left 3, up 15

• y= -(x+3)²+15

• y= -(x+3)² - 15

• y= (x+3)²+15

• y= -(x+15)²+3

In vertex form, y= a(x-h)²+k, what effect does the k have on the graph?

• Translates vertically (up or down)

• Translates horizontally (left or right)

• Dilates (stretches)

Which description best fits the transformation of f(x)=x² into f(x) =(x-5)²+3 ?

• Opens up, shifts to the right 5, and shifts up 3

• Is narrow, shifts left 5 and up 3

• Shifts right 5 and down 3

• Opens down and shifts up 3

What transformation happens here: y = (x - 5)² - 3?
