CCSS.HSN.RN.A.2

If f(x) = (x - 1)² + 2 which function below represents h(x) if h(x) = f(x - 4) + 2?

• x² - 8x + 18

• x² - 10x + 21

• x² - 10x + 29

• x² + 6x + 13

Consider the following statement:

If x is irrational and y is irrational, then x + y is irrational

Determine whether the statement is always true, sometimes true, or never true.

• Never true. The sum of two irrational numbers will always be rational.

What is the axis of symmetry for a quadratic function?

• The vertical lines that go through the x-intercepts.

• The vertical line that goes through the vertex.

• The horizontal line that goes through the vertex.

• The horizontal line that goes through the y-intercept.
