• stretch, left 4, down 5

• reflection, left 4, down 5

• reflection, shrink, left 4, down 5

If the blue graph is
f(x) = x² 
the red must be...

• g(x) = (x + 3)²

• g(x) = (x - 3)²

• g(x) = x² + 3

• g(x) = x² - 2

• 0

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

• Shifts the function left or right

• Reflection over the x-axis

• Vertical stretch or compression

• Shifts the function up or down

• g(x) = x² + 5

• g(x) = (x - 5)²

• g(x) = (x + 5)²
